Introduction: On the 11th-12th, the cliff-like cooling, a new round of cold air hit, and heavy rain and heavy rain were distributed in the following areas
Affected by the residual circulation low-pressure system of Typhoon "Sea Anemone", it is expected that some places in central and southern Guangdong, central and southern Guangxi, Hainan Island and other places on the mainland will continue to rain, and the magnitude is not small, there will be heavy to heavy rain, local heavy rain weather process.
It should be noted that with the arrival of the Bailu solar term, cold air in the northern region has become more frequent. From the weather forecast from September 10-12 issued by the Central Meteorological Observatory, the cooling area mainly covers the eastern part of the northwest region of the mainland, the eastern part of the southwest region, the north of North China, the northeast region and other regions, the cooling range is 4~8 °C, and the local area is cooled by 10 °C.
Some people may say that cooling by 4-8 ° C has no effect, and the weather is quite hot. However, the impact on farming is significant. Because, crop maturity mainly depends on accumulated temperature, the accumulated temperature is not enough crops can not mature, if continuous rain will lead to insufficient accumulated temperature, the grain is not full, affecting the yield. Even, in severe cases, the last thing the farmer gets back is a handful of grass.
Of course, this wave of cooling is not only in the north, but also in parts of western China. For example, from the afternoon of the 11th, Chongqing will usher in a significant cooling rain weather, with a maximum cooling of 10-12°C expected. Although people feel less hot, for crops, sudden low temperature will make them grow abnormally, causing diseases and pests, which farmers need to pay attention to.
Here's a look at the weather forecast for September 11-12:
From the weather forecast No. 11-12, rainfall is mainly concentrated in the western part of the northeast region of the mainland, the central part of Heilongjiang, the eastern part of Tibet, the southeast of the northwest region, the western part of Huanghuai, the western part of Jianghuai, the eastern and western part of Jianghan, the eastern and northern part of the southwest region, the southern part of Sichuan, the southern part of South China and Hainan Island, and the weather process of heavy rain and heavy rain in local areas. Please refer to the table below for details:
By September 12, there were moderate to heavy rains, local heavy rains or heavy rains in parts of the mainland such as western Huanghuai, most of Jianghuai, eastern Jianghan, north-central and southern Jiangnan, eastern and southern southwestern China, and southern and western South China. Please refer to the table below for details:
As the direct sunlight continues to move south, the nights in the northern hemisphere are getting longer and longer every day, the temperature difference between day and night increases, and the temperature drops day by day.
Continuous rainy weather can cause the incoming crop to lodg, mold or germinate, causing serious damage. Therefore, for farmers, it is still hoped that the weather can be hotter, leaving the crop a longer growth time, which will make the grain fuller, the weight of 1,000 grains higher, and thus obtain higher yields.
As the old saying goes, "white dew is early, cold dew is late, and the autumn equinox is just right to plant wheat", and the autumnal equinox is about to usher in the autumnal equinox, and there is also rainy weather at this time, which has an impact on sowing overwintering crops such as wheat.
