What should Huang Meitian pay attention to?

The weather in early summer is getting more and more lively every day. In recent days, there have been strong convective weather such as strong winds, short-term heavy rains, hail and thunderstorms in our city. There are two reasons for this changeable weather. First, the surface temperature is relatively high recently. The temperature at the bottom is high, the warm air rises, it is cold during the rising process, and the atmosphere is extremely unstable, which is prone to strong convective weather. In addition, the subtropical high is strengthened, a large area of warm and humid airflow is active, and cold air is transported from the north. When the temperature is cold, it will naturally rain.

According to the Municipal Meteorological Observatory, the weather in our city has been mainly cloudy in recent weeks, and the temperature has remained at 20-30℃. 12 and 16 have showers or thunderstorms. There will be more thunderstorms near Meiyu period, which is different from the frequent rainy days in Meiyu period. However, according to the analysis of the latest meteorological data, because the meiyu situation has not yet been established, the standard of meiyu period is that the ridge line of subtropical high jumps northward to 20 degrees north latitude and remains stable for more than 10 days. At this time, the subtropical high controls the middle and lower reaches of the Yangtze River, and there is more and more rain, forming plum rain. The annual average plum blossom date in our city is June 14, and the plum blossom date is July 7. According to the forecast of the Municipal Meteorological Observatory, this year's rainy season will be mainly process-oriented, with less rainy season, 170-230mm (262.8mm for the whole year). Due to the combined action of cold and warm air, the precipitation concentration increased during the plum flood season. The main disastrous weather is waterlogging caused by continuous rainstorm and local heavy precipitation, as well as strong lightning, strong wind and hail caused by strong convective weather. Yangmei should pick early rice in time and beware of pests and diseases. Once in May, severe weather will increase significantly. Around June 25th, bayberry on Jianshan Mountain in our city will enter the picking period. The city agricultural station reminds the majority of fruit farmers to seize the fine weather and pick them in batches at the right time. After picking, the application of organic fertilizer should be increased in time to restore the stone of Myrica rubra and enhance the stress resistance of the tree. At present, our city has planted single-season late rice. It is necessary to do a good job in the field management of single-season late rice seedling fields in time, prevent the influence of heavy rain on sowing and seedling, strengthen the management of fertilizer and water after sowing, and promote the healthy growth of seedling. In the hot and rainy season, it is necessary to do a good job in the detection, early warning and prevention of pests and diseases; When the rain stops and the weather clears, the temperature rises quickly, and we should also be wary of the adverse effects of excessive greenhouse temperature on crops. Beware of "weather syndrome" in rainy season. Huangmeitian will also affect human health. According to meteorologists, about one-third of people react more strongly to the stimulus of the weather than others. Hot and humid weather is prone to migraine, gastric ulcer, cerebral thrombosis and rash, which is called "weather syndrome" in medicine. Statistics show that when the humidity increases, many people will lack self-control and be agitated. At the same time, with the decrease of air pressure, the blood pressure, erythrocyte sedimentation rate and urine volume of human body will change slightly, which is easy to induce corresponding diseases. Therefore, doctors remind the public that according to the weather forecast, "high-risk groups" such as heart disease and high blood pressure should take some preventive measures or consult doctors about preventive measures.
