The KBDI is an estimate of the soil moisture deficit, which is the amount of water necessary to bring the soil moisture to its full capacity. A high soil moisture deficit means there is little water available for evaporation or plant transpiration. [2] This occurs in conditions of extended drought, and has significant effects on fire behaviour.
The Palmer drought index, sometimes called the Palmer drought severity index (PDSI), is a regional drought index commonly used for monitoring drought events and studying areal extent and severity of drought episodes. [1] The index uses precipitation and temperature data to study moisture supply and demand using a simple water balance model.
The GPCC drought index provides SPEI datasets at a 1.0° spatial resolution for limited timescales (1, 3, 6, 9, 12, 24, and 48 months). [5] Inputs to SPEI datasets can include high-resolution potential evapotranspiration (PET) from the Global Land Evaporation Amsterdam Model (GLEAM) and hourly Potential Evapotranspiration (hPET). GLEAM is a set ...
(The Center Square) – California Gov. Gavin Newsom and the Biden-Harris Administration reached a long-awaited agreement on the updated rules for the State Water Project (SWP) and the Central ...
Intrinsic water-use efficiency W i usually increases during soil drought, due to stomatal closure and a reduction in transpiration, and is therefore often linked to drought tolerance. Observatios from several authors [3] [6] [7] [8] have however suggested that WUE would rather be linked to different drought response strategies, where
In the wake of a biblical blizzard that unloaded nearly 100 inches of snow on California, AccuWeather is making a major announcement: California will be free of widespread drought through at least ...
The U.S. Drought Portal also aggregates and presents drought impact data for economic sectors such as agriculture, energy, water utilities, and recreation using interactive maps and data. [11] The NIDIS Program is supported by the NOAA Climate Program Office and is housed at the NOAA Earth System Research Laboratories in Boulder, Colorado.
No one lives in drought areas as of the latest update, a roughly 900,000 decrease from August. California is 100% drought free ahead of a wet El Niño winter. See latest conditions
