weather forecast, what does the blue warning mean?
China Meteorological Bureau announced the Trial Measures for Issuing Early Warning Signals of Sudden Meteorological Disasters. The measures stipulate that whenever sudden disastrous weather such as typhoon, rainstorm and high temperature comes, the public can see new warning signals from TV, radio, Internet, mobile phone short messages and electronic display boards located in prominent positions in cities. At present, there are 11 kinds of sudden meteorological disasters that issue early warning signals: typhoon, rainstorm, high temperature, cold wave, fog, sandstorm, thunderstorm and gale, hail, snowstorm and road icing. Early warning signals are generally divided into four levels. According to the severity and urgency of the disaster, the colors are blue, yellow, orange and red, which respectively represent general, heavy, serious and particularly serious.
level 1 is very unlikely; Level 2 is less likely; Level 3 is more likely; Level 4 is highly probable; Level 5 is very likely; 2. The rainfall data table causing geological disasters is Grade 3, which is the attention level in the forecast (heavy rain: 38.-74.9 mm); Level 4, which is an early warning level in the forecast (rainstorm: 5.--99.9mm, easy to cause geological disasters); Level 5, warning level in the forecast (heavy rain: 1-25 mm); Level 1-2, notify the land and resources department to master; Grade 3-5, the county land and resources bureau jointly with the county meteorological bureau put forward the short-term forecast and imminent disaster forecast, submitted to the county * * * and released to the public, and notified in place step by step according to the county, township, village, hidden danger point leaders and monitors. III. Rainfall classification standard: (calculated in 24 hours) 1. Heavy rain: 25.-49.9mm2, large-. 25mm description: the warning signals of disastrous weather are divided into eleven categories: typhoon, rainstorm, high temperature, cold wave, fog, thunderstorm and gale, sandstorm, hail, snowstorm and road icing. The warning signals are generally divided into four levels, and the colors are blue, yellow, orange and red in turn according to the severity and urgency of the disaster.
