A New Weighting Scheme in Weighted Markov Model for Predicting the Probability of Drought Episodes

, 2018
Drought is a complex stochastic natural hazard caused by prolonged shortage of rainfall. Several environmental factors are involved in determining drought classes at the specific monitoring station. Therefore, efficient sequence processing techniques are

Utilizing Objective Drought Severity Thresholds to Improve Drought Monitoring

Journal of Applied Meteorology and Climatology, 2020
AbstractDrought is a prominent climatic hazard in the south-central United States. Drought severity is frequently classified using the categories established by the U.S. Drought Monitor (USDM). This study evaluates whether the thresholds for the standardized precipitation index (SPI) used by the USDM accurately classify drought severity.
