The index uses precipitation and temperature data to study moisture supply and demand using a simple water balance model. [ 1 ] [ 2 ] [ 3 ] It was developed by meteorologist Wayne Palmer, who first published his method in the 1965 paper Meteorological Drought [ 4 ] for the Office of Climatology of the U.S. Weather Bureau .
The primary science benefit of the NOMADS framework is that it enables a feedback mechanism to tie Government and university research directly back to the NOAA operational communities, numerical weather prediction quality control and diagnostics processes at NCEP, and climate model assessments and inter-comparisons from around the world.
Known for its glowing swaths of yellow, orange and red, the U.S. Drought Monitor has warned farmers, residents and officials throughout the nation of impending water scarcity every week since 1999
The other moisture conditions are dry, AMC I or , and moist, AMC III or . The curve number can be adjusted by factors to C N I I {\displaystyle CN_{II}} , where C N I {\displaystyle CN_{I}} factors are less than 1 (reduce C N {\displaystyle CN} and potential runoff), while C N I I I {\displaystyle CN_{III}} factor are greater than 1 (increase C ...
A version of WRF-NMM tailored for hurricane forecasting, HWRF (hurricane weather research and forecasting), became operational in 2007. [9] In 2009, a polar optimized WRF was released through the Byrd Polar Research Center at the Ohio State University. [10]
On NOAA's HeatRisk tool, the scale ranges from 0 or green, meaning little or no risk from expected heat, to 4 or magenta, which indicates extreme and/or long-duration heat-related impacts.
Moisture dew point is the temperature at which moisture condenses out of a gas. This parameter is inherently related to the moisture content, which defines the amount of water molecules as a fraction of the total. Both can be used as a measure of the amount of moisture in a gas and one can be calculated from the other fairly accurately.
The scale of dBZ values can be seen along the bottom of the image. dBZ is a logarithmic dimensionless technical unit used in radar. It is mostly used in weather radar, to compare the equivalent reflectivity factor (Z) of a remote object (in mm 6 per m 3) to the return of a droplet of rain with a diameter of 1 mm (1 mm 6 per m 3).
