How to judge the wind direction in weather forecast

How to "get out of the oven": First, collect meteorological data. At the same time every day, the staff collect the observation data of meteorological elements at the county meteorological station, transmit them to the National Meteorological Center, and participate in the exchange of meteorological information between the whole country and the world.

Secondly, the National Meteorological Center processes the data according to the meteorological data collected by various places, plus the data collected by meteorological satellites and weather radars, and forms numerical forecast products and weather situations (weather maps), which are fed back to the meteorological departments of various places.

Then, according to the local conditions, the forecaster of the county meteorological bureau comprehensively analyzes and judges the weather map fed back by the National Meteorological Center to form a local weather forecast conclusion.

Specific analysis: numerical forecast+traditional weather map+approaching forecast.

numerical forecasting

However, the numerical forecast of wind speed is used to grasp the transit time of weather system.

Specific to the wind speed, refer to the numerical forecast to know an approximate wind speed range, and also know the longitudinal configuration at that time.

. The same transit system is different in winter and summer, different in day and night, and sometimes momentum downward transmission needs to be considered.

This is very important considering the terrain. For example, in Xi 'an, the cold wind does not blow the northwest wind after crossing the border, but blows the southeast wind because of the influence caused by the unique terrain.

Approximation forecast is to consider the punctual data of upstream stations, and the revised forecast is very effective.

Think about everything clearly. It may seem complicated, but there are priorities. Taking care of primary and secondary factors and influencing factors, in fact, wind forecasting is better. (Hehe, compared with this crazy thing like advection fog)
