How high is the temperature? Specific degrees!

When the temperature is above 35℃, it can be called "high temperature weather", and if the highest temperature exceeds 35℃ for several days, it can be called "high temperature heat wave" weather.

Among them, the standard of high temperature yellow warning signal is: the daily maximum temperature is above 35℃ for three consecutive days; The standard of high temperature orange warning signal is: the maximum temperature rises above 37℃ within 24 hours; The standard of high temperature red warning signal is that the maximum temperature rises above 40℃ within 24 hours.
