Near Real-time Seasonal Drought Forecasting and Retrospective Drought Analysis using Simulated Multi- layer Soil Moisture from Hydrological Models at Sub- Watershed Scales
This study proposes a stratified approach of drought severity assessment using multi-layer simulated soil moisture. SWAT (Soil and Water Assessment Tool) models are calibrated for 50 watersheds in the South-Atlantic Gulf region of the Southeastern US and a high-resolution daily soil moisture …

An Integrated Drought Index (IDI) Incorporating Physical and Social Aspects
… social variables that can be integrated into a drought index to predict areas susceptible to drought. Severe drought events are capable of causing millions of dollars in damage. The 1988 drought caused the United States approximately $40 billion in damage. Drought forecasting, modeling, and …

Soil Moisture-driven Drought Evaluation under Present and Future Conditions
Drought is one of the most severe natural disasters and detrimentally impacts water resources, agricultural production, the environment, and the economy. Climate change is expected to influence the frequency and severity of extreme droughts. This dissertation evaluates drought conditions using a …

Drought assessment and forecasting using a nonlinear aggregated drought index
This study developed an objective drought assessment tool through a Drought Index (DI), and then developed a drought forecasting tool using the developed DI to forecast future drought conditions. These tools can be used to assist water managers to assess droughts effectively and forecast future …

A Multi-Scale Study of the Nexus of U.S. Droughts: Predictability, Mechanisms, and Awareness
Drought is one of the least understood natural hazards, in part due to the complexity of the generating mechanisms that interact across a range of spatiotemporal scales. Alarmingly, every year, droughts continue to cause billions of dollars in economic losses. To constrain these losses, there is a …

Soil Moisture Dynamics and Thresholds for Surface Energy Balance Regime Transitions: An Observational Analysis at a U.S. Grassland Site
… implications for land surface model development, drought forecasting, and vegetation response assessments under a changing climate.

Development and analysis of a homogeneous long-term precipitation network (1850-2015) and assessment of historic droughts for the island of Ireland
… rainfall reconstructions a 250-year historic drought catalogue is established using the Standardised Precipitation Index (SPI). Documentary sources, particularly newspaper archives, spanning the last 250 years are used to (i) add confidence to the quantitative detection of drought episodes and …

Learning-Based Modeling of Weather and Climate Events Related To El Niño Phenomenon via Differentiable Programming and Empirical Decompositions
… it focuses on ENSO’s effects on rainfall and drought conditions in two major regions shown to be linked through the strength of the dependence of their climate on ENSO: 1) the southern Pacific Coast of the United States and 2) the Nile River Basin. In these cases, drought and rainfall are tied …
