Significance of meteorological early warning:
The timely release of early warning information will help crops "escape" dry and cold, and also remind people to pay attention to travel arrangements. Blue, yellow, orange and red signals are the source of early warning and safety. Meteorological information "early warning" can guide people to travel. The early warning signal levels of the same meteorological disaster are different, and the corresponding defense measures are also different.
People make reasonable arrangements for travel through meteorological disaster warning signals. Yang, deputy chief engineer of the early warning room of the Public Meteorological Service Center of China Meteorological Administration, reminded that when you see the lowest warning signal, you should carefully consider the plan of traveling, outing or going to low-lying areas and pay attention to the weather changes at any time.
