Weather forecast warning color

Brief introduction of weather warning signals Early warning signals are divided into eleven categories, such as typhoon, rainstorm, high temperature, cold wave, fog, thunderstorm and gale, gale, sandstorm, hail, blizzard and road icing.

Early warning signals are generally divided into four levels (IV, III, II and I). According to the severity and urgency of the disaster, the colors are blue, yellow, orange and red in turn, and they are marked in Chinese and English, representing ordinary, heavy, serious and particularly serious respectively. According to the characteristics and early warning ability of different disasters, the early warning grades and standards of different disasters are determined. When a variety of meteorological disasters occur or are expected to occur at the same time, a variety of early warning signals can be issued simultaneously according to the corresponding standards.

Lushan Mountain is 1400 meters above sea level. According to the formula that the temperature drops by 0.6 degrees every time the altitude rises 100 meters, it is assumed that the altitude at the foot of Lushan Mountain is 50 meters, and the temperature at the top of the mountain is 8-9 degrees lower than that at the foot of the mountain. If the foot of the mountain is 30 degrees, the top of the mountain is 22 degrees. This temperature is definitely a good place to escape the summer. Coupled with the strong airflow on the mountain, the wind on the mountain is very strong and the summer is very comfortable and pleasant.
