How often is the air pressure warning set?
The setting frequency of air pressure early warning is 4hPa/3hr, that is, the early warning will be triggered when the air pressure drops or rises for 4hPa every 3 hours. The setting frequency is determined according to the needs of meteorological monitoring and forecasting. The change of air pressure can provide important meteorological information, which is of great significance to weather forecast and climate change monitoring. By setting the air pressure alarm frequency, the change of air pressure can be monitored in time and corresponding measures can be taken when necessary. This frequency setting can help meteorological departments and related institutions to better understand the meteorological situation, improve the accuracy and timeliness of meteorological forecasting, and thus provide better services and guarantees for people's lives and work.
