Institutional setup of the National Weather Service of the United States

The local branches of the National Weather Service are divided into six regional headquarters (East, Central, South, West, Alaska and Pacific), and the local branches are mainly divided into three types:

There is a 122 meteorological forecasting office, which is responsible for providing forecasting and early warning services for the public, coastal waters, fire prevention work and major airports in the area under its jurisdiction. In addition to issuing forecasts and warnings to the public, it is also responsible for contacting county and city emergency agencies, law enforcement units, mass media and volunteer observers in the region. There is a 13 river forecasting center, and the hydrological and meteorological personnel on duty are responsible for monitoring the river flow and water level within their respective jurisdictions, and issuing river water level forecast and flood warning when necessary. The river forecasting center is also responsible for estimating the soil water-holding capacity of all river basins in China, and then issuing "flash flood guidance" for meteorologists to refer to when calculating whether it is necessary to issue flash flood warning or warning. The central meteorological service unit is located in the Federal Aviation Administration 2 1 ARTCC, which is responsible for providing aviation-related meteorological information to the Aviation Administration and coordinating the forecasting and early warning services of major airports and airspace with AWC and various meteorological forecasting offices in the region.
