The latest weather forecast in August: There are still many precipitation, and 1 to 2 typhoons will directly or indirectly affect Jilin Province

Since the beginning of this year, Jilin Province has abnormal climate. It has entered the rainy season in the summer. Since the flood in the flood, there have been abnormal precipitation. Obviously the rainfall process is frequent, and the precipitation is extremely extremely extreme. It is expected that the temperature in August is close to perennial year, and there are many precipitation, and 1 to 2 typhoons directly or indirectly affect Jilin Province; there will be disasters such as heavy precipitation or regional rainstorm and local floods. Farmland waterlogging.

Since this year (January 1-July 30), the province's climate characteristics are: slightly higher temperature, obvious changes in phases, significantly more precipitation, and uneven time and space distribution. Overall, the province's climate is abnormal.

Since the flood in the flood, the precipitation is extremely large, with strong extremes and early rainy season. Since June 1, the average precipitation of the province has been 402.1 mm, which is 67%more than usual. It has been 2nd in the same period of history. In the past 66 years, it is 1st in the rain. During the period of obvious rainfall, heavy rain, and strong rainfall extremely extreme. There have been 6 significant scope of obvious precipitation weather. Thirty counties (cities) appeared in heavy rain, breaking through the historical heavy rain. Four towns, including Daan United Township, have a strong rainfall with a daily rainfall of more than 200 mm. Entering the rainy season on June 4, 14 days earlier than usual.

This year's weather and climate abnormalities are mainly due to the influence of the atmospheric circulation phase fluctuations and the impact of the La Nina incident.

From the perspective of the atmospheric circulation, in June, Eurasia's mid -to -high latitude circles flowed a large direction, and the cold vortex in the northeast was active. In conjunction with the favorable water vapor transportation, the precipitation in Jilin Province was abnormal. Since July, it has been affected by the north and sufficient water vapor conditions in the northeast cold vortex, typhoon water vortex, and subtropical high pressure, and the precipitation is still too much.

The direction of mid -to -high latitudes in mid -May has increased, and the East Asian trough is strong in west, which has led to obvious climate fluctuations in the province, frequent cold air, and low temperature in mid -term. Affected by the cold vortex in the Northeast in June, the temperature was still low.

Since this year, the La Nina incident has continued to affect, which is one of the reasons for the occurrence of low -temperature and rainy rain and rain in the spring of Jilin Province in the spring of Jilin Province.

Judging from the latest meteorological data analysis, the La Nina incident will continue in the future, and the Western Pacific subtropical high -pressure north will help Jilin Province to continue to develop strong precipitation weather.

It is expected that the average temperature in the province in August is 21-22 ° C, which is similar to the same period of the same year. Among them, the west is slightly lower and other regions are slightly higher. The average precipitation in the province is 140 to 160 mm, which is slightly more than the same period of the year, and the distribution of precipitation space is unevenly distributed. There are 20 % to 30 % more in Siping, southern Jilin, Tonghua, and Baishan area, and about 10 % more in other areas. There will be 1 or 2 typhoons directly or indirectly affect Jilin Province. In the central and southern regions, disasters such as heavy precipitation or regional storms and local floods will occur, and may cause flood geological disasters, urban waterlogging or farmland waterlogging.

It is expected that the main precipitation weather is 6 times during the month: August 1, 3-5, 7-9, 14-17, 19-22, 25-26.

It is expected that the precipitation process in August is large, and there will be a typhoon. There may be regional rainstorms and local heavy precipitation in the central and southern parts. Pay attention to preventing flood disasters such as urban waterlogging, farmland waterlogging, local floods, and floods of small and medium rivers. It is necessary to defend the landslides, floods, mudslides and other geological disasters.

In August, there are still many strong convection weather. Pay attention to the local meteorological disasters such as heavy precipitation, lightning, and hail.

In early August, high temperatures may occur in most parts of the province. Pay attention to heatstroke prevention and cooling.
