On the 24th, a group of meteorological information released by Dehui Meteorological Station attracted the attention of Chang Zhaogang, the head of Chang Zhaogang Planting and Breeding Cooperative, the main tobacco producing area in Dafangshen Town, Dehui City. The forecast indicates that there will be short-term severe convection weather within 24 hours. Please do a good job in hail suppression in this area.

On the 24th, a group of meteorological information released by Dehui Meteorological Station attracted the attention of Chang Zhaogang, the head of Chang Zhaogang Planting and Breeding Cooperative, the main tobacco producing area in Dafangshen Town, Dehui City. The forecast indicates that there will be short-term severe convection weather within 24 hours. Please do a good job in hail suppression in this area. The cooperative members shall prepare quickly and set up hail suppression operation sites in time. "Tobacco is afraid of hail, and thunderstorms and hailstones are common in summer, so it is very important for us to make a weather forecast that is accurate to a small scale!" Chang Zhaogang said.

Chang Liqiu, director of Dehui Meteorological Station, introduced the working process of this accurate hail suppression system - the weather radar completes body scanning every 6 minutes. According to the radar echo indicators at different stages of cloud development, combined with the live monitoring data of satellites and regional automatic weather stations, the operational cloud area was comprehensively analyzed and determined, and the cloud height, intensity, thickness, etc. were calculated, The operation direction, operation mode and ammunition consumption are finally determined, and the operation is carried out through the "weather modification operation command system".

"We will prepare and submit the Weather Forecast for the Next 7 Days a week in advance to give the trend forecast of the weather process. Before the extreme weather such as typhoon and rainstorm comes, Dehui Meteorological Station will strengthen the linkage with Changchun Meteorological Station, guide Dehui to make weather forecast and release important meteorological information in time. The weather forecast is accurate to the rain falling area of the township one day in advance, enters the disaster facing fine meteorological early warning state six hours in advance, and issues the quantitative forecast accurate to the township one hour in advance. " Chang Liqiu said.

Crops planted in the open air are greatly affected by the climate. At present, it is in the field plant protection period. All regions in our city have taken effective protective measures according to the characteristics of crops to ensure that crops grow in a suitable environment. But in the process of implementation, there must be specific meteorological data as a reference to ensure the healthy growth of crops. It is understood that the agricultural Internet of Things application platform in our city includes an intelligent agricultural meteorological station. Professional meteorological monitoring equipment has been applied to agricultural production, reflecting meteorological changes with data, making agricultural safety services more in place, and further improving the ability of modern agriculture to prevent and control meteorological disasters.

According to Li Wendong, deputy director of Changchun Agricultural Information Center, the smart agricultural meteorological station is an integrated meteorological station, which is easy to install and operate. The agricultural meteorological station is mainly composed of meteorological sensor heating, collector and transmission module, solar panel, support, etc. In recent years, with the development of planting agriculture, many large-scale agricultural planting areas have introduced intelligent agrometeorological stations to monitor agrometeorological changes. The meteorological factors that can be monitored by the intelligent agrometeorological station include temperature, humidity, wind speed, wind direction, rainfall, solar radiation intensity, etc., so that people can timely understand the changes of agrometeorological information and improve planting efficiency.
