如何观察天气
(i)生活中的天气
1。头晕
天空中有一个高云。当阳光或月光穿过云层的冰晶时,它将在太阳或月球周围产生五颜六色的光环。光环的颜色在内部红外紫色中分类。这些七色的环被称为太阳光环或月球光环,统称为Halo。其中,观察者打开的角度半径为22度的光环是最常见的,称为22度光晕。有时,角度半径为46度的光环和其他形式的光弧类似于光晕。尿布出现仅是因为有一个盘绕的云,云层通常距离前雨区几百公里。随着前部的发展,雨水区可能很快就会移动,因此头晕通常成为多雨天气的前身。
2。Hua
天空中有一层半透明的云层,云中的水滴甚至大小。如果它是由冰晶组成的云,则冰晶的大小必须为甚至。在传输云层的过程中,它被均匀的云滴(水滴或冰晶)衍射,该云液滴将形成一个彩色环,周围的月亮或月球周围的紫外线,称为Hua,称为Hua。因为阳光太亮,所以人们很难观察到阳光,而且月光更为普遍。靠近月球板的花也称为树冠。通常,冠层的紫色不是很突出,因此内环是蓝蓝色,外部主要是黄色,外部为红色。有时,在树冠外面分离黑眼圈之后,将有一个与冠层相同的颜色排序的同心光环,但亮度较弱,称为sub-hua。
3。彩虹和霓虹灯
太阳射线包含七个彩色灯,水滴(雨滴或雾滴),它们射入大气中。在各种彩色的灯光进行折射和反射之后,它们可以在雨帘或雾幕上形成彩色的弧形环。当弧形环打开观察者的角度半径约42度,而光环的颜色类型为内紫外线红色,称为彩虹。在彩虹的外面,有时会出现彩色彩虹弱的彩色光环。光环的角半径与观察者约52度。彩色环的顺序与彩虹相反,即内部红外紫色,称为霓虹灯或次级彩虹。
洪和尼必须背着阳光,然后才能观察到它们。在夏季晚上,当西方晴朗并且东天空有云和雨时,最有可能看到彩虹和霓虹灯。
4.黎明和暮光
在日出之前,在太阳暴露在地平线上之前,太阳在上层大气上闪耀,太阳散布在大气分子上,使天空略微明亮,地面略微明亮。从这一刻到太阳暴露在地平线上的光被称为黎明。
日落之后,即,在太阳下沉到地平线以下之后,仍然有一段时间,阳光可以闪耀到高空的气氛中。由于空气分子的散射,天空和地面仍然是明亮的。在此期间的光称为暮光。
黎明和暮光共同称为黎明和暮光。黎明时期称为黎明,暮光时期称为黄昏。由于黎明开始的标准和暮光之端,通常将其分为平民黎明暮光,海洋黎明暮光和天文黎明暮色。在晴朗的日子,太阳在地平线以下约7度时,民间黎明开始,暮光结束;大约12度,海洋黎明开始,暮光结束。大约18度,天文黎明开始,暮光结束。暮光持续到赤道的最短时间,并随纬度的增加。
(ii)听民间谚语以了解天气
异常的气候变化事件将始终给人们留下深刻的回忆和思想。古代中国人精心观察到异常的气候条件,例如严重的寒冷和气候变化以及形成民间谚语。
“夏天有一个奇怪的高温,冬天有一个奇怪的寒冷。”在夏季和秋季,当太平洋台风击中时,它会使田野中的鱼死于阳光。人们认为那一年温度升高了,冬季有严重感冒的迹象。
“奇怪的热量会导致奇怪的感冒。”这意味着,如果温暖在冬季之后持续,一旦冷空气向南延伸,冷却可能会严重持久。从较长的时间看,世界已经连续几年保持温暖,因此您必须关注最终会来的寒冷冬天。
“一天温暖,夜晚很冷,东中国海也干。”这主要是指半月内的天气。通常,在冷空气中笼罩着冷浪,整天的天气晴朗,因此白天和黑夜之间的温度差很大。
“奇怪的感冒会导致奇怪的干旱。”奇怪的感冒本身表明,干燥和冷的空气非常强大,大气循环状况有利于持续频繁地向南移动冷空气,温暖而潮湿的空气缩小并撤退到外海。这种情况通常是持久的。如果降雨推迟到今年,它将导致冬季和春季的持续干旱。在历史上,许多严重的冬季和春季与早期的严重感冒有关。
“很早就很冷,很早就热身了。”如果最冷的时期明显是升级的,那么在同一个冬天通常不容易出现,这也表明季节将相应地延长,春季可能会早。
(iii)如何预测天气?
世界,山脉和河流都是法律,但是阴,阳,风,雨,太阳,太阳和黑暗是如此之大,以至于这个世界上的人们通过气象部门的预测来了解这一点。尽管它很方便,但也有一些人由于各种原因而无法及时了解它。而且,有很多人无法及时学习。出乎意料的是,人们疏忽大意。一旦他们失去了科学和技术服务,他们就不会依赖或任何自然常识。他们不会被困在路上吗?乡村农民没有手表,所以他可以告诉一天中的时间。山区和森林中的人们没有信息,因此他擅长衡量天气的变化:这取决于人,而不是事物,而其他人则是由于实践经验所致。
为了促进游客,我们特别选择了我们的前任的经验以将它们聚集在一起以供参考:
1。在凌晨,在太阳出现之前,看看东方的黑云,例如鸡头,龙头,旗帜,山脉,山脉,战车,马,星星,鱼类,鱼,蛇,蛇,蛇形,牡丹,牡丹或紫色黑色的空气渗透到那天,那些在阳光下上下阳光的人会下雨,大部分在13点至17点之间。
2.在晚上,看看月亮的颜色,无论是蓝色还是红色,第二天都会有雷暴。月球周围有白云,形成圆形的光线,或那些像车轮一样大的云层(月球光环),这意味着将来有强风。所谓的“太阳是朦胧的,月亮是朦胧的,风是朦胧的。在哪里有衰落的地方,风在哪里?”还说“月亮是朦胧的,风是潮湿的,地基是湿的,地基是多雨的。”如果粉底湿润,柱子是水滴渗出的,这意味着当场会下雨。根据现代情况,有些人总结了“风暴热和管道会产生雨水”,也就是说:突然的热量持续了几天,一两天内会有强风,水滴从自来水管,以及那些被擦掉后仍然渗出的人,一两天之内会下雨。
3。星星闪闪发光,风肯定会表现出来。白云覆盖了大型北斗星2至4个小时。 “天堂发生变化,水面生长靛蓝。”夏季,苔藓在水的底部生长,水变成靛蓝,这意味着大雨。当水闻到泥土或芬芳的味道时,雨就会到来。当下雨时,如果泥浆闻起来很浓烈,就很难在一两天内清除。
4。在第一个月球第七天和第八天,北风肯定会爆发。在月历的第二个月的第三天,三月的Qingming节,四月和6月12日的夏至。
(iv)“风来了,雨来了”
“风来了,雨来了”是众所周知的天气变化现象。通常在夏季更常见。从降水类型来看,它应该是对流雨中降水的一种更特殊的形式。它形成的一个非常重要的前提是,它是由相邻地区强烈的热量,大规模空气上升,水蒸气凝结和对流降雨形成的。它的特征是:风必须来自降水区,雨水与风相来。通常,范围很小,持续时间很短,强度很高。大多表现为雷暴。在我国家南部仲夏的“双重抢”季节中,人们常常会因突然的风和雨而措手不及。
这种风是如何形成的,雨是如何出现的?
首先,风的形成和到达主要是由热性质差异引起的。当某个位置强烈加热时,空气会膨胀并升起并导致对流降雨,天空中的云层削弱了到达地面的太阳辐射热,尤其是在大量降雨量下降之后。
加强大气的冷却水平。这将导致温度迅速下降,空气密度增加以及气压增加。但是,相邻的区域仍处于高温,低空气密度和低气压的热量。这样,在同一水平面上有一个气压梯度,这会导致大气从高压区流到低压区。这产生了从降水开始向相邻区域开始的区域吹来的。这就是“风来”的原因。
其次,从降水的角度来看,它主要与气流及其活动的性质有关。上面提到的风的到来当然可以促进云的运动,并加速降水的到来。但这只是减少的条件,而不是主要原因。当降水开始强烈冷却的区域中的大气时,在仍会接收热量的相邻区域形成了较冷且较重的气流。随着气压的增加,这种较冷的气流会迅速移动。在运动期间,我们遇到了我们经过的区域的温暖和轻型气流。此时,温暖而轻的气流迅速爬上了冷却器和较重的气流。在上升过程中,冷却并迅速形成沉淀时,水蒸气凝结。这可能是因为雨水随风的到来!
(5)知道风的天气
“东风带来潮湿,西风干,南风吹动,北风发冷。”这种谚语在长江的中部和下游循环,这表明不同的风将带来不同的风雨,例如温暖,温暖,干和潮湿。
长江的中和下游毗邻东方的海洋和西部的大陆。这里的风向东和向西吹,向南和向北行驶,并负责传达冷热和运输水蒸气的任务。东风潮湿,南风温暖。温暖而潮湿的东南风为产生云和雨水提供了丰富的水蒸气条件。只要有上升的机会,云就会凝结和降雨。因此,有些人说:“您需要问雨的距离,但要看东南风”和“白天的东南风,晚上湿plive”。西风干燥,北风很冷,西北风在晴天吹来,表明西北风将继续晴天和寒冷。西北风在下雨天吹来,表明干燥和冷空气已被压下。随着冷空气层变厚,空气中的云层升起且较薄。很快,乌云就会消失。因此,谚语说:“西北风打开了高空锁。”
在温带区域,如果地面上有两对风,它们通常是两个冷和加热气流,范围很大,范围很大,温度和湿度。南风带有温暖而潮湿的空气,而北风则带有干燥和冷空气的流动。在他们遇到的地区,形成了前线。在正面,温暖而潮湿的空气是最剧烈的上升运动。有时,温暖而潮湿的气流是强大的,并积极地向北攻击,超过冷气流,向上滑动,冷却凝结的云。目前,天空中的云(温暖气流)与地面上的风(冷气流)相对。 “靠风,肯定会有降雨。”随着云层的发展迅速而变厚,形成了广泛的云和雨水。有时,干燥和冷空气的力量比温暖和潮湿的空气强。它需要主动攻击,就像插入空气下方的楔形物一样,将温暖和潮湿的空气向上抬起,并且前面出现了一束雷暴的云层。在这一地区,雷声和闪电咆哮,风和雨水暴风雨。
额叶和雨带的生长和运动取决于南北气流力的生长和恶化。强风在某个地方吹来,这意味着该地方位于前云和雨带的南部。目前,温暖的前部向北走,天气晴朗而温暖。但是,“北风不被南风欺负”,“南风吹到末端,北风又回到礼物”,“南风猛烈吹来,风和雨将很快上升。”每当南风吹来时,尽管阳光明媚又温暖,也表明北风将冷锋推向南部。因此,一旦“北风变大了”,乌云就会涌动,下雨将降落。南风吹得越长,这意味着温暖和潮湿的气流积累的强度更强。一旦北部的冷空气向南移动,就越有可能出现拔河的情况,从而导致前部在该地区向北和南方旋转,并持续持续,形成了连续的雨天的准静态额叶天气。因此,有一个说法:“如果您刮擦东南,您将无法完成半个月。”如果冷空气非常强大,那么向南的寒冷阵线和云层和雨水经常扫过,并立即被推到南大洋。北风越强,阳光越长。因此,“当南风降临时,天气雨,北风到来时晴天。”
高气压和低气压的运动通常通过风吹。如果在高压控制下晴天没有风,则意味着高压系统尚未显着移动,并且晴天持续;如果低压系统上没有风,则意味着低压系统很少移动,因此继续下雨。长压系统的降水系统在扬兹河的中部和下游大部分从西方移动,因此雨前的风向大多是向东的,并且逆时针逆时针方向,也就是说,风向从东南 - 东北变化;相反,如果风向是从东南向西变化,通常不会下雨。只有当夏季出现流行的云层云时,才有可能下雨。谚语说:“东风都在所有四个季节中,恐怕东风不会吹太多。”这表明低压系统之前的局部风向会影响。还有一个说法:“东风将在雨后诞生,将来下雨会更加凶猛”:也就是说,在雨水停止之后,仍然会有3或4级的东风降雨中止的迹象表明,西方仍然有低压力移动,将来会更加努力。雨。
一般而言,东北风开始的降雨将持续很长时间,降雨也很高。如果即将下雨或开始下雨,风向有时是东北的,有时是东南,这被称为“同时两种风”。这表明移动的低压系统的范围很大且运动缓慢,并且将来会有不断的降雨。
在雨天,如果风向向西转动,天气将大部分变成晴天。西北风向是,风力越大,阳光转的速度越快,太阳持续的时间就越长。有时,西风很小,天气仍然没有引人注目。 “东风,西风晴天;西风不晴天,将是多云的情况。”如果它在南风或西南风中变成阳光,那么很长一段时间内通常不会晴天,这表明下一个雨期很近。
有时,东方风会连续两到三天吹来,而且天气保持不变,但风吹得越来越紧。这种情况通常发生在干旱的日子里。此时,温度为“温暖的白天和晚上寒冷”,人们称之为“东风干旱”,“东风将是寒冷和干旱”。当低压控制当地时,东风不强,旋风经常在下午在地面附近发生,这表明最近发生了干旱。 “东风吹了,西风吹了,需要半个月的时间才能下雨。”这意味着风向有时是向东,有时在一两天之内向西向西,这表明在中期不会有强大的天气系统入侵,也不会降水。
值得注意的是,相同的风不一定具有相同的天气。要查看风和天气,我们必须查看特定条件。
首先,这取决于季节。在夏季,加热气流比冷气流强。当东南风吹时,前云和雨带向北推动。目前,在扬兹河中部和下游的单个供暖流的控制下,空气缺乏运动的条件,因此有一个说法:“每年三个季节东风和雨是只有东风和阳光明媚的夏季风和阳光明媚的夏天。”如果夏季季风在太平洋亚热带高压的稳定控制下普遍存在。尽管夏季季风来自东南海,但高压控制下的气流稳定,天气晴朗,炎热和多雨,因此“东南风是干的和干燥的”。如果西北风在夏天吹来,它将表明下雨,因此有谚语,例如“冬天的西部是阳光明媚,夏天的西部是多雨”和“夏天的北部大风”。
在半年的冬天,冷空气比温暖的空气强,西北风经常将额叶和雨带推向南大洋。此时,在单个冷空气的控制下,天气很晴朗,就像谚语“秋天后在西北的田野”和“春天的西北田野,阳光明媚;冬天在西北部的阳光,太阳会变成晴天。”如果是这种情况,东南风吹了,但没有持续很长时间,就是这样
“南风吹到末端,北风来返回礼物”,表明前云和雨带影响了当地,天空将变得多云。 “你必须问雨的距离,但看东南风。”
其次,这取决于风速。谚语说得很好:“东风在下雨,恐怕它太优雅了。”只有当东风咆哮白天和黑夜时,风才能“强烈,雨水很快”。只有当东南部收紧时,雨才能“快速而苛刻”。在冬季和干旱中,东风将需要两到三天的下雨。如果风达到5级或六级,则可能会在一两天内下雨。在初夏和雨季,只要东南风吹来,它就会下雨。此外,“风是雨的头,风很强,雨将关闭。”淋浴前,风通常是第一个撞到头部的风,风首先吹来,然后雨水降落。当雨水停止时,风将首先增加,然后雨再次停止,也就是说:“大雨的强风避难所”。这种现象发生在云层云下。因为当云母云云接近多雨区域时,会先风,然后下雨。当风很重时,多雨区将迅速通过。
第三,注意当地。有必要区分“真风”和“假风”。在正常情况下,风向和风速在不同地方的每日变化都不同。这种正常的每日变化模式不能反映天气系统的影响,被称为“假风”。只有当风向沿特定方向稳定并且风力逐渐增加时,才能预测天气变化的“真风”。通常,“真正的风”将从早晨到晚上从傍晚到午夜吹来。尤其是夜风,这将更好地预测天气中明显的转折点。至于当地山谷的风,它们也是“假风”,不能用于预测天气转弯。
气候与健康
(i)天气影响男孩和女孩的诞生
婴儿的出生日期与天气有关;在实施生命统计数据的所有国家,婴儿的诞生季节都显示出明显的统计规则。以日本为例。在一月和三月,诞生的婴儿人数最多,而7月的婴儿人数最少。双胞胎大多出生于下半年。气候对胎儿的性别有一定的影响。 1977年在英国出生的男性和女性婴儿的比例为140:100。著名的生物学家通过大量调查和研究指出,这与1975年至1976年英国的严重干旱一致。这与大雨有关。 1952年在伦敦发生异常雾气后的320天,许多当地医院报告说,出生的女孩比例比男孩高24%。
分娩和个性月份:统计数据表明,在最冷的月份出生的人具有很强的可塑性,并且在任何领域都易于成功。夏季出生的人往往会内向。
(2)寒冷和天气
在我国许多地区,感冒被称为“冷”,这表明感冒与天气状况密切相关。感冒全年都会发生,冬季和春季是频繁的时期,因为流感病毒容易在低温,干燥和寒冷的环境中寄生。传统中药还认为,当气候突然变化并且寒冷和温暖异常时,风邪恶病毒最有可能侵入人体。
临床实践还表明,每当发生“天气突变”时,感冒的人数通常会突然增加。 “天气突然变化”主要反映在气象因素(例如温度,气压,降水,风和湿度)的急剧变化中。它们通常是由前天气系统(即冷空气质量和供暖空气质量之间的界面)带来的,尤其是在春季的冬季,北部的冷空气不时地向南移动,正面向南移动活动更频繁,通常会引起感冒或其他症状。
患有感冒的人的症状因季节而异。所谓的“四个季节冷”:风冷(由风冷却或春季冷却引起),风热(由春季的高温或秋季和冬季升高引起),湿或热冷(维持冷(维持)在夏季和高温下加热),干燥(由秋季干燥的空气引起)。前两个感冒症状是总体头痛,发烧,鼻塞和流鼻涕,而第三个感冒通常伴有胸部紧绷,关节疼痛和其他症状。干燥的寒冷通常伴随着干鼻和喉咙,咳嗽没有痰液或症状,例如痰,口渴和红色舌头。
因此,“适应自然”应该成为预防感冒的主要原则。具体而言,有必要在熟悉当地天气和气候变化法的前提下聆听和观看天气预报计划。当天气突然变化时,及时换衣服和被子,并保持温暖,以防止感冒感冒。在突变后一两天内的天气中,尽可能少的地方去公共场所,以防止感冒感染。
(iii)气候如何“形状”人类
一个人的外表,性格和行为不能完全由人类本身统治。这种“力量”有时在自然界的“棕榈”中持有。
一个人的身高,肥胖,薄,红色,黑色和白色的外观不仅与人类遗传学有关,而且与气候有关。
在欧亚大陆,由于较高的轻度和高温,居住在赤道附近热带地区的人们的皮肤深色。为了抵抗炎热的气候,他们的脖子很短,头部显然很小,鼻子很宽,有利于在体内分散热量。在寒冷和温带地区的高纬度地区,阳光全年都无法直接在阳光下闪耀,光强度很弱,温度非常低,并且严重的寒冷时期很长。他们中的大多数是白人。为了抵抗严重的寒冷,它们通常比居住在温暖和热带地区的鼻子更钩住鼻子。鼻子的桥更高,鼻子中的孔更长。就头部形状而言,寒冷和温带地区的居民具有较大的头部,圆形形状和扁平面,这非常有利于绝缘和减少散热。
为了适应山脉的稀薄空气,山区的居民具有突出的胸部和呼吸功能,其肺容量和最大通风量明显高于沿海地区。气候对高度的影响更为明显。以我的国家为例,北京的年度阳光小时为2778.7小时,广州的年度阳光小时为1945.3小时,成都的年度阳光小时只有1239.3小时。因此,这些城市居民的平均身高又又是。从高到短。原因是阳光下的紫外线可以将人皮中的脱氢胆固醇变成维生素D的主要来源,并可以促进骨钙化和厚度的骨骼钙化和生长。
居住在热带地区的人们花费更多的时间户外活动。高温使人们住在那儿,容易发生烦恼和愤怒。居住在寒冷地区的人们大部分时间都在一个狭小的空间中与他人一起度过,发展一个可以控制自己的情绪并具有强烈耐心的角色。例如,生活在北极圈中的爱斯基摩人被称为“永远不会生气的人”。居住在温暖而宜人的水镇中的人们对周围的事物敏感,热情而敏捷,聪明和敏捷,因为潮湿的气候和美丽的风景。由于山区居民拥有广泛的山脉和人口稀少的地区,因此他们在这个环境中生活了很长时间,大声说话,具有诚实,直截了当的人物。居住在广阔草原上的牧民,因为草原是巨大的,交通不便,气候很恶劣,风和沙子非常强壮,因此他们经常骑马和壮成长,他们的个性变得大胆,直截了当,并且变得直截了当,并且热情好客。
(iv)热岛效应和人类健康
在“热岛效应”的影响下,整个城市的云和雾将增加,导致有害的气体和烟雾在城市上积聚,从而造成严重的空气污染。人类的许多疾病是由“热岛效应”引起的。
医学研究表明,环境温度与人体的生理活性密切相关。当环境温度高于28度时,人们会感到不舒服。甚至更高的温度很容易导致烦躁,中风和精神障碍。当温度高于34度(伴随着频繁的热浪冲击)时,它也会引起一系列疾病。特别是,心脏,脑血管和呼吸系统疾病的发生率显着增加,死亡率显着增加。此外,高温可以加快光化学反应的速度,从而增加大气中有害气体的浓度并进一步损害人类健康。
在“热岛效应”的影响下,城市每个地方的温度不同,但呈现封闭的高温中心。 In these high-temperature zones, the air density is small and the air pressure is low, which is easy to generate cyclonic upward air flow, allowing various surrounding exhaust gases and chemically harmful gases to continuously replenish the high-temperature zone. Under these harmful effects, residents in high-temperature areas are very susceptible to digestive or neurological diseases. In addition, the number of respiratory diseases such as bronchitis, emphysema, asthma, sinusitis, and pharyngitis has also increased.
The serious urban heat island effect not only affects people's normal life and work, but also becomes a constraint on the further improvement of people's quality of life and the further development of cities. Therefore, studying technical methods to reduce the urban heat island effect and taking various measures to alleviate the impact of the heat island effect is of great significance to improving people's quality of life and maintaining sustainable urban development.
Diet and geographical environment
From the perspective of staple food structure, due to the different hydrothermal conditions, the northern part of my country mainly planted wheat and the southern part of rice, thus forming a pattern of "north-to-south rice". In addition, the cooking skills of China's "eight major cuisines" have their own characteristics, and they are known as "sweet in the south, salty in the north, spicy in the east, sour in the west", and their formation is also related to the geographical environment. Take the formation of "sweet south and salty north" as an example, it is related to the climate differences between the north and south of our country. Northern my country is located in a warm temperate zone, with cold and dry winters, high and rainy summers, and the temperature varies greatly every year. In the past, even a small amount of vegetables was difficult to survive the winter, and at the same time, they were reluctant to "squander" for a while, so northerners pickled the vegetables. "Enjoy" slowly, and thus, most people in the north have developed the habit of eating salty food.
The south is rainy, the light and heat conditions are good, and sugarcane is abundant. Compared with the north, vegetables are recommended several times a year. Southerners are "surrounded" by sugar, so they naturally develop the habit of eating sweets. It's not that northerners don't like sweet food, but sugar was rare in the past, so they had to use “salty” instead of “sweet” to adjust their taste. Although the north is not short of sugar now, once the taste is formed, it cannot be changed overnight. Shanxi people can be jealous and can be said to be the first of the "western sourness". Fujianese and Guangxi people love to eat sour bamboo shoots. The more sour they are, the more they can show the producer's level. Dai people also like to eat sour chicken, sour bamboo shoots and chicken is a traditional famous dish. Why do "Western people" in Shanxi and other places like to eat sour food? The reason is that the water and soil in the Loess Plateau, Yunnan-Guizhou Plateau and its surrounding areas contain a large amount of calcium. Therefore, their food also has a higher amount of calcium. In this way, through diet, calcium deposits can easily occur in the body and form stones. After long-term practical experience, the working people in this area have found that eating more acidic foods is conducive to reducing diseases such as stones. Over time, they gradually developed the habit of loving sour food. "Guizhou people are not afraid of spicy food, Hunan people are not afraid of spicy food, Sichuan people are not afraid of spicy food."
The food customs that like spicy food are mostly related to the humid climate and geographical environment. The eastern part of my country is located on the coast, and the Koreans in the northeast are also humid and rainy, with many spring and cloudy weather. Although Sichuan is not in the eastern part, it is located in the basin and is even more humid and foggy. The sun is rarely seen all year round, so there is " Shu Tai barks the sun”. This climate causes the surface humidity of the human body to be comparable to the saturated air humidity, making it difficult to discharge sweat, making people feel bored and uneasy. Over time, it can easily cause people to suffer from rheumatism and cold evil, spleen and stomach weakness. If you eat chili peppers and sweat all over, sweat can of course be easily excreted. Eating spicy food regularly can drive away cold and dampness, nourish the spleen and stomach, and is extremely beneficial to health (for locals).
Meteorological knowledge
1. "Three days of heavy fog, there will be heavy rain."
Heavy fog refers to heavy fog. The heavy fog lasts for three days, indicating that the warm and humid air flow is particularly strong. The stronger the warm and humid air flow, the heavier the rain will be when the cold air arrives. Therefore, the proverb that heavy fog will cause heavy rain in three days is used to predict the weather, and the accuracy is relatively high no matter which season.
2. Why do thunderstorms occur in summer and spring different times?
In spring, people are mostly awakened by the rumbling thunder in the middle of the night to the morning when they are sleeping, which is called "Spring Thunder Shocking Dream". In summer, thunder is rarely heard in sleep, because most summer thunderstorms occur from afternoon to evening. So why do thunderstorms occur differently in the day in spring and summer?
Thunderstorms are generated when strong convective movements occur in humid air, and their occurrence is closely related to the stability of the atmosphere.
In summer, on sunny and windy days, the ground is exposed to strong sunlight, which heats the air near the ground. The closer it is to the ground, the higher the temperature rises. The afternoon is when the ground temperature rises the highest, and the atmosphere is the least in the day. During a period of stability, the development of strong convective movements is the fastest at this time. If the air is very humid and the water vapor is abundant, then there will be thunderstorms from afternoon to evening this day. This kind of thunderstorm formed by strong heat on the ground is called a thermal thunderstorm. From midnight to morning, the ground temperature drops to the lowest level and the atmosphere tends to stabilize, so hot thunderstorms are not easy to form.
Thunderstorms occur in spring differently than in summer. In summer, hot thunderstorms are often caused by the same heating mass. The weather is clear the day before the thunderstorm, while spring thunders mostly occur in areas where the cold and cold air mass confronts. When the two cold and warm air groups in the north and south confront each other, the warm and humid air crawled on the back of the cold air, and a large amount of water vapor was condensed, making the sky cloudy, it rained for days, and there was no sunshine on the ground all day long, so that the temperature could not rise very high during the day. The temperature cannot drop very low at night, and the daily changes in temperature are very small. But at the top of the high-altitude clouds, the sun is still exposed to sunlight during the day, and the daily changes in temperature there are relatively large. During the day, the clouds are hot in the sun, and the temperature is prone to rise. The atmospheric head becomes lighter, the stability increases, and the possibility of thunderstorms becomes smaller; at night, the clouds dissipate heat to space, and the temperature at the upper part of the clouds drops, especially From midnight to morning, the temperature drops the lowest during the day. The head of the atmosphere becomes heavier and tends to be unstable. Convection movement develops in this cloud layer, forming thunder and lightning and heavy rain. This is the reason why spring thunders appear in the middle of the night to the morning.
Strategies for refuge in the wild
① Preparation for typhoon prevention
The prerequisite for preventing typhoons is to get a typhoon warning in advance and to fully prepare solutions before the typhoon comes. People are quite fragile in the face of typhoons. It is recommended that if they have to stay in the surrounding population gathering areas and get help. Typhoons often cause disastrous consequences such as muddy roads, landslides, broken trees, and flooding, which are not something that individuals can resist.
Wind protection, rain protection and cold protection are all basic principles for protecting typhoons. Quickly go to a hut or cave to take refuge. If there is no such place, choose to have no concerns about landslides or flood attacks. For example, highlands, under rocks or in forests are safer shelter places. If you have to continue moving forward, you must also bend your body and do not get caught in the rain. The damp clothes will take away your body temperature and cause physical imbalance. When encountering strong winds, try to lie on the ground and escape to the forests, and do not hide under the dead trees.
② Avoid avalanchetracks and climb. It is best to go southwards or westwards for long valleys, as avalanches occur less frequently. When climbing the valley wall, you should cross the woods between two avalanche routes.
