2022谷雨过后天气还会冷吗 谷雨过后是不是就热起来了

导语：从节气的排位来看，谷雨排在第六位，也是春季节气的最后一位，这就意味着，谷雨过后，我们便迎来了夏天。但这仅是天文上的含义，而在气候上，谷雨之后还不是夏天。那么，2022谷雨过后天气还会冷吗？一般谷雨过后是不是就热起来了？下面我们一起来了解。

　2022谷雨过后天气还会冷吗 谷雨过后是不是就热起来了

　谷雨过后天气

　谷雨前后气温会出现大幅度的上升，一般地区都不会冷了，但是具体的还是要依据你所在地方的天气预报来看。

　众所周知谷雨是春季的最后一个节气，也是气温正式回升的一个分水岭，谷雨过后，气温会越来越高。谷雨节气后降雨增多，雨生百谷。雨量充足而及时，谷类作物茁壮成长。谷雨时节的南方地区，"杨花落尽子规啼"，柳絮飞落，杜鹃夜啼，牡丹吐蕊，樱桃红熟，自然景物告示人们：时至暮春了。这时，南方的气温升高较快，一般4月下旬平均气温，除了华南北部和西部部分地区外，已达20℃至22℃，比中旬增高2℃以上。

　谷雨的时候天气以温暖为主，气温基本上稳定在20°左右。

　谷雨前后气温大概多少度是很多人都有的疑问，不过依照往年来看每每再此期间除了北部和西部部分地区外，已达20℃至22℃，比中旬增高2℃以上。华南东部常会有一、二天出现30以上的高温，使人开始有炎热之感。低海拔河谷地带更是已进入夏季。

　谷雨节气正值暮春时节，白天气温回升较快，但昼夜温差较大。所以大家要想再此期间出行的话建议大家多拿一件外套御寒。另外谷雨节气后降雨增多，空气中的湿度逐渐加大，此时我们在养生中应遵遁自然节气的变化，针对其气候特点进行调养。同时天气转温，室外活动增加，但这时杨絮、柳絮四处飞扬，过敏体质的朋友应注意防止花粉症及过敏性鼻炎、过敏性哮喘等。也可每天早晚用冷水洗鼻和揉搓鼻翼，可改善鼻黏膜的血液循环，有助缓解鼻塞、打喷嚏等过敏性鼻炎症状。

　谷雨气候特点：

　谷雨气候

　风沙

　按照二十四节气，谷雨是春季的最后一个节气，处在暮春时节的谷雨，意味着春将尽，夏将至，冷空气大举南侵的情况比较少了，但影响北方的冷空气活动并不消停。

　4月底到5月初，气温毕竟要比3月份高得多，土壤干燥、疏松；空气层不稳定，上层风动量下传，锋面气旋活跃，共同引发的大风、沙尘天气比较常见。

　1993年、1995年、1998年、2005年的谷雨期间，都出现了强沙尘暴、沙尘暴。其中，1993年5月5日发生在甘肃省金昌市的黑风，瞬时最大风速达34米/秒(12级)，能见度陡降为零，风沙形成的沙暴壁高达300-400米，上下有三层结构，每层有一球状尘团滚动，最下层呈现黑色，中上部红黄相间，以每小时90公里的速度自西向东移动，各地的气温急剧下降，最低气温降到-2-2℃。造成人员重大伤亡和经济损失，至今令人毛骨悚然。

　大范围的浮尘天气，昏黄的天空，落下的黄尘，让诗人所描绘得草长莺飞、花红柳绿、春意盎然的景象黯然失色。

　春旱

　淮河流域是江南春雨和北方春旱区之间的过渡地区，从秦岭、淮河附近向北，春雨急剧减少。

　谚语云：“清明谷雨雨常缺”，意思是说，在这两个节气期间，雨水紧缺。谷雨期间，海南岛、川西、广西西部、西北、华北的人们更加渴望雨水，一般年景，晴天多、日照强、蒸发大、多风沙、空气干，此时的雨水更是贵如油。越冬作物冬小麦、油菜等进入成熟期需要雨水，春天播下的谷子、玉米、高粱、棉花、蔬菜等，也要有雨水才能根深苗壮，茁壮成长，此时下场透雨，就相当于是在下粮食啊！

　如果冬季降雪少，容易出现旱象。对于十年九春旱的地区，取节水灌溉、实施人工增雨等措施就显得十分重要了。

　春旱也是林草火灾的帮凶，林区加强林火监测，防火宣传，可以说是到了紧要的阶段。

　谷雨天气特点

　强对流天气

　一般来说，4～8月是一年中强对流天气的高峰期。进入5月，在南方的许多地区，局部的雷暴、冰雹、狂风、龙卷等灾害性天气会明显增多。防雷、防雹、防风提上日程。

　大暴雨

　在我国长江中下游、江南一带，往往开始明显多雨，而特别是华南，一旦冷空气与暖湿空气交汇，往往形成较长时间的降雨天气，也就进入了一年一度的前汛期。云雨中夹裹着的强对流天气，不仅会带来冰雹、雷暴等灾害性，有的还会伴随着短时间的、局地的大暴雨或特大暴雨，24小时的雨量可达300或400毫米以上，造成江河横溢和严重内涝，而时间较长的暴雨还会引发泥石流、山体滑坡等灾害。

沙尘暴天气的危害有哪些？

沙尘暴的危害一是大风，二是沙尘。其影响主要表现在以下几个方面。

1.风蚀土壤，破坏植被，掩埋农田。

2.污染空气。

国家环保总局的监测网显示，2002年强沙尘暴当天，北京每平方米的落尘量达到了20克，总悬浮颗粒物达到了每立方米11000微克，超过了国家标准的十几倍，超过正常值的100倍。

3.影响交通。

沙尘暴对交通的影响主要表现为，一是降低能见度影响行车和飞机起降，如韩国2002年有7个机场被迫关闭，3月21日约有70个航班被迫取消。二是沙尘掩埋路基，阻碍交通。据《华商报》报道，由于沙尘暴掩埋了部分铁路，造成乌鲁木齐开往西安的列车中途遇阻。

4.影响精密仪器使用和生产。

5.危害人体健康。

沙尘暴引起的健康损害是多方面的，皮肤、眼、鼻和肺是最先接触沙尘的部位，受害最重。皮肤、眼、鼻、喉等直接接触部位的损害主要是刺激症状和过敏反应，而肺部表现则更为严重和广泛。7年前美国健康学家首先提出，细微污染颗粒与肺病和心脏病死亡之间存在关系。澳大利亚《时代报》称由于土壤被风蚀而引起的沙尘暴是导致该国200万人哮喘的元凶。

6.引起天气和气候变化。

沙尘暴影响的范围不仅涉及我国有些省份，而且影响到了韩国和日本；1998年9月起源于哈萨克斯坦的一次沙尘暴，经过我国北部广大地区，并将大量沙尘通过高空输送到北美洲；2001年4月起源于蒙古的强沙尘暴掠过了太平洋和美国大陆，最终消散在大西洋上空。如此大范围的沙尘，在高空形成悬浮颗粒，足以影响天气和气候。因为悬浮颗粒能够反射太阳辐射从而降低大气温度。随着悬浮颗粒大幅度削弱太阳辐射(约10%)地球水循环的速度可能会变慢，降水量减少；悬浮颗粒还可抑制云的形成，使云的降水率降低，减少地球的水。可见，沙尘可能会使干旱加剧。

7.生态环境的恶化。

出现沙尘暴天气时狂风裹的沙石、浮尘到处弥漫，凡是经过地区空气浑浊，呛鼻迷眼，呼吸道等疾病人数增加。如1993年5月5日发生在金昌市的强沙尘暴天气，监测到的室外空气含尘量为1016毫米/立方厘米，室内为80毫米/立方厘米，超过国家规定的生活区内空气含尘量标准的40倍。

再看看下面的这些统计数据，让我们意识到防治沙尘暴的紧迫性。

全国有1500千米铁路、3万千米公路和5万千米灌渠由于风沙危害造成不同程度的破坏。

近几年来，我国每年因风沙危害造成的直接经济损失达540亿元，相当于西北5省区1996年财政收入的3倍。

科学家们做过推算，在一块草地上，刮走18厘米厚的表土，约需2000多年的时间；如在玉米耕作地上，刮走同样数量的表土需49年；而在裸露地上，则只需18年时间。

常年四五月份正是我国北方沙尘暴高发期，请您密切关注天气预报，提前做好预防沙尘暴的准备。

沙尘暴、海啸、地震形成的原因

现代科学对地震的成因作了以下解释：

由于地球在不断运动和变化，逐渐积累了巨大的能量，在地壳某些脆弱地带，造成岩层突然发生破裂，或者引发原有断层的错动，这就是地震。

地震绝大部分都发生在地壳中。

地震共分为构造地震、火山地震、陷落地震和诱发地震四种。

构造地震是指在构造运动作用下，当地应力达到并超过岩层的强度极限时，岩层就会突然产生变形，乃至破裂，将能量一下子爆发出来

海啸是指由海底地震，火山爆发和水下滑坡、塌陷所激发的，其波长可达几百公里的海洋。它在滨海区域的表现形式是海水陡涨，骤然形成“水墙”，伴随着隆隆巨响，瞬时侵入滨海陆地，吞没良田和城镇村庄，然后海水又骤然退去，或先退后涨，有时反复多次，造成生命财产巨大损失。本地海啸在海啸波到达前：还常伴有强烈的地震或震灾发生。我国也是多风暴潮灾害的国家，历代都把风暴潮和地震海啸所表现的潮位异常混称为海啸、海溢或大海潮等。近20年多年来，我国学术界决定把风暴和地震引起的潮位异常分别称为风暴潮和海啸。另外，有时把天文、风暴和地震原因造成潮位异常所引起的滨海地区受淹导致的灾害统称为 “潮灾。但多数情况下，所谓潮灾就是习惯地指风暴潮灾害。大洋中海啸震源附近水面最初的升高幅度只有1至2米，这种洋波移行在深水大洋时，波长可达几十到数百公里，周期之至200分，最常见的是之至狈分，传播速度可达近千公里／小时。所以海啸不会在深海大洋造成灾害甚至难于察觉这种波动。然而当海啸波进入大陆架后，因深度急剧变浅，能量集中，引起振幅增大。若大陆架很窄，从海面到海底流速几乎一样的海啸波携带巨大能量直冲岸边或港湾，波高骤增，这时可能出现波幅为20--30米的巨浪和造成波峰倒卷。这种冲到那里，那里便是一片废墟，也正是这些地方，海啸才变为生命的最大威胁和可怕的自然现象。

有关研究指出沙尘暴的形成必须具备四个条件：一是地面上的沙尘物质，它是形成沙尘暴的物质基础；二是大风，这是沙尘暴形成的动力基础，也是沙尘暴能够长距离输送的动力保证；三是不稳定的空气状态，这是重要的局地热力条件，沙尘暴多发生于午后傍晚说明了局地热力条件的重要性；四是干旱的气候环境，沙尘暴多发生于北方的春季，而且降雨后一段时间内不会发生沙尘暴是很好的证据。春季沙漠的边缘地区，由于长期干旱，而且地表少有植被覆盖，当有大风来临的时候地表的沙尘很容易被吹起且被输移，但由于沙子粒径较大，不易形成悬移(悬浮移动，是小颗粒物质保证长距离输移的必要条件)，因此不能长距离输移，这也是距沙尘较远的地区只有降尘而少见扬沙的主要原因。如果风持续的时间很长，形成悬移的浮尘能够被输送到很远的地方，所经过的地区就会出现沙尘暴；当风速减弱到一定程度后，浮尘就会降落，该地就会出现降尘天气。如果此时降水，就会形成所谓的“泥雨”。

从沙尘暴形成过程所需的四个条件看，黄土高原、广袤的沙漠及由人为因素的破坏正处于荒漠化过程中的土地，北方春季末耕种的土地及处于施工过程中的基础设施(如高速公路等)为沙尘暴的发生提供了充分的物质源；而春季北方地区的干旱，又使沙尘暴发生的可能性增强；大风的产生是一种复杂的大气现象，主要是冷锋活动或经纬向环流调整作用的结果。由此可见沙尘暴的产生是多种复杂因素共同作用结果，人类活动对自然界的破坏导致土地荒漠化的加剧，对沙尘暴发生产生了极其重要的作用，而近几年全球干旱(其原因目前尚未知)等异常天气现象也对沙尘暴的发生起了不可估量的作用。所以说人类活动对沙尘暴的产生只起到一定作用，并不能说沙尘暴就是人为因素造成的。
