Not all Ching can have rain-bright, weather-IT information

About to enter the tomb-sweeping day, that even primary school students can carry "Tomb Sweeping Festival have rain" again brainwashed. However, rainstorms in South partners represents, and this year more than "rains", while "the rain rushing" and small partners in the struggle in the North, rain clear can clear you have a name? This time, we′ll pick a steak around the Ching Ming Festival are "rain".

Most of the South "rain" occasionally "rain rushing"

Clear, not just one outing tomb sweeping holiday, it was a solar term. From the throttle on the qingming Festival on April 5-April 19, it was in early April. Data di PA 1961-2010 these 50 years is representative of provincial capital cities in the South during the Ching Ming Festival period of rainfall data.

In this 15 days every year, 0.1 mm or more rain on the day of our day, a rainy day, to look at the probability of gas during the Ching Ming Festival day of rain in the South.

Can be found, in addition to being outside the dry season in Yunnan, South of the middle and lower reaches of the Yangtze River during Ching Ming rain days generally more than half. On behalf of South Changsha and Nanchang appeared the probability of rain is more than 60%, Ching is often "rainy days not open" scene. On behalf of Fuzhou, Guangzhou in South China to be outdone, because April is the start of flood season in South China, rain will gradually rise. Ching Ming rain are common features in the South.

In the South during this rainy day, majority drizzle and moderate rain, rain is not strong, it is consistent with ancient poetry is described in the "rainy" scenes. However, occasionally heavy rain or rainstorms in some places, it became stronger, such as Nanchang, Changsha, Guangzhou, heavy rains or rainstorms around 15% per cent.

Statistics from torrential rain days, probably 2-3 in Nanchang during the Ching Ming Festival period will be caught in a heavy rain, Changsha, Guangzhou is about 5-year flood event, the frequency is still relatively low.

In this occasional days of rainfall, most of the time under a day to more than 100 mm, or heavy orders of magnitude, this rain is definitely "the rain rushing".

North almost "rain break" some "snow"

In the North, Ching Ming rain probability significantly smaller than the South, each day of rain precipitation is relatively less, seems to appear in northern China during the Ching Ming Festival, "rains" is not much, the probability of a lot of places not to 20%.

So, for large parts of the North, is almost "Tomb Sweeping Festival is rain break" this with the North at this time of warm and dry weather conditions coincide.

Of course, Heilongjiang, Inner Mongolia and other more northerly areas, it might be this season in April snow, or "Tomb Sweeping Festival is Xue."

From poems to find the one that fits the "rainy"

Far away in the Liang dynasty, it was recorded: during the Spring Festival, two days before the cold food festival, often with "wind rain." If driving during the Spring Festival, the rainy day, it is called "pouring rain of fire", or "rain". When the tomb of Tang dynasty poet du Mu wrote, should be a day like this.

Although Tang is not as easy as the modern climate data, data is managed from the pile of books and research materials in the digs the next Bao. According to the book the Chinese climate change: during the reign of the Sui and Tang dynasties, and monsoon regions in Eastern China rendered "four wet" clip "Mitate" features four wet-ad 590 ~640, 710-year ~740 year, 810, 880 ~900 years ~820 years.

Dualla (du Mu and Li Shangyin and said "little Li Bai and Du Fu"), born in 803, died in 852, 828 Wed scholars in Luoyang and embarked on careers. It can be said that in a period of relatively moist climate in China in his youth, data speculated that he will have more opportunities to experience the "Tomb Sweeping Festival have rain." However, after his official China′s overall climate became dry.

Qingming, a poem was read for him politically marginalized, in 842 for became later. 842-852, he is in the East of Hubei, southern Anhui and northern Zhejiang provinces spent, which is South of the huaihe River to the South North. According to the Chinese book on climate change, in sui and Tang dynasty on the Yangtze River in the year 620 ~840 overall in the wet state. Du Mu was able to catch the tail of this wet period, wrote the poem circulated through the ages.

Braised for a long time is trying to tell you, "Ching Ming Festival pours" kind of in the South, especially in Hubei, Anhui, Hunan and other places, and occasionally run into "the rain rushing". Northern is basically "qingming rain break" track dry needed precautionary fire.

不是所有清明时节都能雨纷纷 - 清明,天气 - IT资讯

马上就要进入清明节气，那句连小学生都会背的“清明时节雨纷纷”又出来洗脑了。不过正在遭受暴雨袭击的南方小伙伴表示不服，今年岂止“雨纷纷”，明明是“雨哗哗”；而北方小伙伴却在纠结，不下雨的清明还能叫清明吗？这次咱们就来扒一扒我国各地清明时节是否都能“雨纷纷”。

南方多数“雨纷纷”偶尔“雨哗哗”

清明，不仅仅是一个踏青扫墓的节日，它还是个节气。从节气上来说，清明一般在4月5日-4月19日前后，正是4月中上旬。数据帝扒出了1961-2010年这50年里南方具有代表性的省会级城市在清明节气期间的降雨数据。

在每一年的这15天里，我们把当天降雨量达到0.1毫米或以上的日子，作为一个雨日，来看看南方在清明节气期间的雨日概率。

可以发现，除了正处于干季的云南之外，长江中下游地区及其以南地区在清明时节的雨日普遍过半。代表江南地区的长沙、南昌出现雨日的概率更是超过60%，清明时节经常是“淫雨霏霏，连日不开”的场景。代表华南地区的福州、广州也不甘示弱，因为4月份往往是华南前汛期的开始，下雨天会逐渐多起来。看来清明时节多雨是南方的普遍特点。

在南方这个期间的雨天里，小雨和中雨又占了大多数，雨势不强，很符合古诗中描述的“雨纷纷”之景。但是有些地方偶尔也会下大雨或暴雨，雨势较强，像南昌、长沙、广州等地大雨或暴雨占比达15%左右。

从暴雨日数统计来看，南昌大概2-3年在清明节气期间会遇上一场暴雨，长沙、广州大概是5年一遇，出现的频率还是比较低的。

在这偶尔来一下的暴雨天中，最厉害的时候一天可以下到100毫米以上，也就是大暴雨量级，这样的雨下起来绝对是“雨哗哗”了。

北方几乎“雨歇歇”有的还会“雪纷纷”

在北方，清明时节雨日的概率明显比南方小，每个雨日的降雨量也相对少一些，看来在清明节气期间我国北方出现“雨纷纷”的情况并不多，好多地方的概率不到20%。

所以，对于北方大部地区来说，几乎是“清明时节雨歇歇”，这与北方在这个季节晴暖干燥的气候状况相吻合。

当然，对于黑龙江、内蒙古等地更加偏北的地区，还有可能在这个时节遇上四月飞雪，也就是“清明时节雪纷纷”了。

从古诗中寻找最符合“雨纷纷”的地方

远在梁代，就有人记载过：在清明前两天的寒食节，往往有“疾风甚雨”。如果正赶在清明这天下雨，就叫“泼火雨”，也就是“清明雨”。唐朝诗人杜牧写下《清明》的时候，应该就是这样的日子。

虽说唐朝的气候数据不像现代这么好找，数据帝还是翻箱倒柜从一堆古籍和研究资料中挖了下宝。《中国历朝气候变化》一书显示：隋唐年间，中国东部季风区呈现“四湿”夹“三干”的特点，四个湿润期为公元590年~640年、710年~740年、810年~820年、880年~900年。

小杜（杜牧与李商隐并称“小李杜”），生于803年，卒于852年，828年二月在洛阳中进士，走上仕途。可以说，他年轻时处于中国气候相对湿润的时期，数据帝推测他从小就有更多的机会体验“清明时节雨纷纷”。不过，他做官以后中国的气候总体变得干燥。

《清明》一诗，被解读为他政治上受到排挤，公元842年外放以后而作。842至852年，他基本都是在湖北东部、安徽南部、浙江北部一带度过，也就是江淮南部到江南北部地区。根据《中国历朝气候变化》一书，隋唐时期的江南地区在620年~840年整体上处于湿润状态。杜牧那时或许赶上了这个湿润期的尾巴，写出了流传千古的诗句。

扒了半天其实是想告诉你，“清明时节雨纷纷”在南方还蛮准的，尤其是湖北、安徽、湖南等地，偶尔还会碰上“雨哗哗”。至于北方，基本上是“清明时节雨歇歇”，天干物燥还需要特别防范火灾。
