Why is Jiaozuo the hottest place in Henan?

Well, first of all, I want to tell you that Jiaozuo was the hottest place in the province last year. The average temperature in the whole summer reached 27.9℃, but I think it is nothing compared with this year. I'm disgusted that there was no electricity in our house last night and no one lived there. I cried to death about the terrible high temperature weather, but I don't understand. It's hot anyway.

Based on the meteorological data of 1990- 1998, this paper analyzes the high temperature weather system affecting Jiaozuo city, so as to grasp the evolution characteristics of the high temperature weather system and improve its forecast accuracy. (*** 1 page)

Key words: high temperature, warm ridge, analysis of continental high pressure weather situation, weather forecast

Article snapshot: On the 500 hectopascal map, the warm ridge is located at110-120. There is a low pressure from Pingliang to Tianshui. Hetao to Mongolia is a relatively warm center, and South China is in a temperature ridge. Or along 100. E has a strong ridge between 40 and 60 N, and the subtropical high is distributed in an east-west narrow strip. The westward extension can choose 1 IOOE, which is stable and less active, which is conducive to keeping the atmosphere dry over the region and in the eastern and southern regions. When a brick vortex forms near Wuhan, and there are warm ridges at L 10- 120 ~ E and 30-50 ~ R, the subtropical high begins to shrink or split eastward, which indicates the adjustment of atmospheric circulation situation and the end of high temperature weather forecast: 24 hours before high temperature appears, at1i5-/KLOC-. From 35 degrees to 40 degrees east longitude, a warm high ridge is formed, and the height extends westward by I 10. E. There is a temperature ridge between the Hetao and the Beihu Lake, and a warm trough appears on the plateau, which passes through the Korean Peninsula to the East China Sea in the northeast to form a deep ice vortex, and its center value is 12 potential meter; In the upstream areas of 100-IIOOE and 35-45N, there are at least four stations with the minimum value of T-) 20℃ and T-I) I3℃, which is basically NW wind, and T-I increases with latitude; 48h before high temperature, 80- 100. ￡、30—50。 There is a warm ridge between N, but the intensity is not great. There is a temperature ridge from Bayu Lake to 50N, which is from I20 to 130. 30 to 50 years old. In the future, there will be a vortex moving south or east in N area to form a thickness detection system, or a warm low pressure in the eastern plateau can guide the warm ridge in the west to move east, which indicates that there will be high temperature weather within 48 hours. Date of receipt: 200 1—0924 Henan Meteorological No.65438+0,2002,2.22700hPa On the map of 700 HPA, the area from the north of the Yellow River to Hetao is controlled by warm high ridge, with temperature >: I2 and height >; 3 12 potentiometer. Once the vortex in Jiangzhun basin moves northward or the vortex near Lanzhou moves eastward, it shows that the focus of high temperature weather forecast is: 24 hours before high temperature appears, at 100- 1 10oE, 30-50 N,115-/. E, there is a brick vortex at 40 ~ 500 north latitude, which is a warm ridge from Jianghuai to Hetao, and it is at 105-I 15. 35 to 45 degrees east longitude. There are 5 stations T- 1 > 12℃ between N, and it increases to the northwest; 48h before high temperature, 105— 1 15. From 35 to 45 degrees east longitude, the T of each station in Zone N is 12℃, forming a warm ridge at 90- 1 10 east longitude and 40-50 north latitude, and at15-120ce4 north latitude. 22385 13 HPA situation forecast focuses on 850 HPA circle. The city's above surname is in) 12℃ Warm Gaoling, which is east of the height center. Central intensity ≥ 148 potential meter. When its intensity weakens, it indicates the end of high temperature weather. Forecast focus: 24 hours. A few hours before the heat. Xinjiang has a warm ridge with a central temperature >; 24℃, 8o-90. E, within 40-500 north latitude, South China and Southwest China are low-pressure areas, and this city is controlled by high pressure, or there is warm low pressure in Xinjiang, with the central temperature of 20℃, 80-I20~E and 35-45. It is controlled by high pressure in North China, South China and Southwest China. The city is located in the low pressure area and the upstream suction area. F) 10℃ 48 hours before the high temperature appeared, vortex formed at110-12ff 'e and 40-50% N, and at 105-6550. There is a warm ridge from 35 degrees to 45 degrees east longitude, and the tongue is warm in the west of the city. 100- 120. Thirty to fifty years old. There are five stations in the warm high area without obvious deep system. ) 10℃ 2.24 the thin prediction of the ground situation focuses on the ground map. Cities are controlled by high or low pressure fields in the west and east. 24 hours before the occurrence of high temperature, the market is in a pressure field that is high in southwest and low in northeast or high in west and low in east. 22.5 Elements of Boxing Station ① During the 24-48 hours before the occurrence of high temperature, the change of clouds was mainly medium-high stability clouds, and the high clouds changed from dense cirrus clouds to cirrus clouds. As the saying goes, "gossamer flies out of the sky, and it can be expected for a long time"; Most of the middle clouds are semi-transparent cumulonimbus clouds, supplemented by cumulonimbus clouds, and the total cloud amount tends to decrease or even be cloudless, which is called "tile clouds, sun people"; Low clouds are usually dominated by stable light cumulus clouds and broken cumulus clouds, which have little effect on the whole high temperature system.
