How is the hail level judged?

The hail warning signal is divided into two levels, which are represented by orange and red respectively. Hail weather warning * * * is divided into two levels, which are represented by orange and red respectively. Among them, the orange warning signal of hail indicates that there may be hail with lightning weather within 6 hours.

Since 1980s, with the wide application of advanced equipment such as weather radar, satellite cloud image receiving, computer and communication transmission in meteorological services, the ability to track and monitor hail activities has been greatly improved. When the local meteorological observatory (station) finds hail weather, it shall immediately notify the meteorological observatory (station) that may be affected.

Meteorological departments at all levels combine modern meteorological science and technology with long-term accumulated forecasting experience to comprehensively forecast the occurrence, development, intensity, scope and harm of hail, and continuously improve the forecasting accuracy. In order to transmit the hail warning information to government leaders and the masses at all levels as soon as possible.

Meteorological departments at all levels issued "alerts" and "emergency alerts" through local radio stations, television stations, telephones, computer service terminals and severe weather early warning systems, which enabled all sectors of society and the broad masses of the people to take defensive measures in advance, avoided and alleviated disaster losses, and achieved obvious social and economic benefits.

Hail is a disastrous weather that harms agricultural production in spring and summer. When hail occurs, it is often accompanied by strong winds, severe cooling and strong lightning. A hail attack, light yield reduction, heavy refusal to harvest. According to the weather map, satellite cloud image analysis and radar monitoring, meteorological stations can make forecasts in advance, but the accuracy is still not ideal.
