The US rainfall map signifies the climatology of the country. The attributes of the U.S. rainfall forecasting are described in the outer parts or joining parts of the country. With the help of a map, it is helpful to recognize where there has been heavy rainfall and where the rainfall is not dense. The amount of sleet can signify within them and it is easier to study the climatical situations. The weather of a region changes day to day or it can change every hour but the climate remains static unless or until any outside storm doesn’t disturb the weather.

By using the various types of the Nilometer also called rain gages such as the non-recording cylindrical container type or the recording weighing type, the float type and the tipping- bucket type. The other way of measuring the precipitation is by the use of Radar. However, the actual measurement taken by the radar is of the backscattered power of the echo returns. This return power is used to calculate a reflective factor, Z. This reflectivity in the form of Z is used in an equation referred to as the “Z-R relationship” to determine the rainfall rate. Then comes the ABRFC.

The ABRFC or Arkansas -Red River Forecast Centre is the center that provides technical support to the National Weather Service’s efforts to provide river and flood forecasts and warnings to protect life and property and provide basic hydrologic forecast information for the nation’s economic and environmental well-being. The ABRFC produces NWS WSR-88D 1-hour radar precipitating estimates for an area of responsibility on an approximate four by four kilometers square grid resolution. The drainage area of the Red River above Fulton Arkansas and the area of the Arkansas River above Pine Bluff Arkansas are responsible areas for the ABRFC.

This contains over 208,000 square miles and takes in the sections of seven states. The NWS’s river forecasting models, also called the National Weather Services, require an areal estimate of precipitation. The models sum up the rainfall-runoff process over the drainage catchment or runoff areas.

The large river basins are subdivided into these smaller catchments or banished zones. The runoff from excess rainfall in each region is used to calculate the streamflow which is used to produce river level forecasts. The measurements of the precipitation of a network can be converted to areal estimates using various techniques.
Rainfall Map of USA
The study proved that global warming is leading to increased precipitation in eastern portions of the U.S. While droughts are becoming common in western regions. The contagious part of the U.S. is east of the 98th meridian. The mountains of the Pacific Northwest, Willamette Valley, and Sierra Nevada range are the wetter portions of the nation.
With the average rainfall exceeding 30 inches per year. The drier areas of the U.S. are Desert Southwest, Great Basin, Valleys of Northeast Arizona, Eastern Utah, and Central Wyoming. Increased warming in urban heat islands leads to increased rainfall downwind of cities.
