Monitoring and predicting the 2007 U.S. drought

New divisions for monitoring and predicting climate

Climatologists have long questioned the accuracy of the current climate divisions (CDs) in the United States in representing regional climate. To address their concerns, we embarked on a long-term effort in 2003 to create a more rational, statistically-based set of national CDs that would help improve drought monitoring and climate forecasting. The result, thus far, is an experimental map of ne...

A Prototype Drought Monitoring System Integrating Climate and Satellite Data

Droughts are natural hazards with varying patterns in space, time, and intensity. Their dynamic character challenges our ability in planning, predicting, monitoring, and providing relief to affected areas. Because of the spatial and temporal variability and multiple impacts of droughts, we need to improve the tools and data available for mapping and monitoring this phenomenon on all scales. A t...

New Climate Divisions for Monitoring and Predicting Climate in the U.S

Evaluation the efficiency of using Artificial Neural Networks in predicting meteorological droughts in north-west of Iran

Drought is one of the most destructive natural disasters in human societies that cause irreparable impacts on agriculture, environment, society and economics. So, awareness of occurrence of droughts can be effective in reducing losses. In this study, in order to modeling and forecasting drought severity in a 37 year time period (1971-2007) in 21 meteorological stations, located in the cold semi...

ارزیابی خشکسالی هیدرو-‌‌ متئورولوژیکی برپایه شاخص تلفیقی خشکسالی و پیش‌‌بینی آن با زنجیره مارکوف در حوضه رودخانه سرباز (جنوب شرق ایران)

Drought is a climatic anomaly that associates with a significant decrease (lack) of precipitation and water resources availability, which spreads on vast temporal and spatial scales, and significantly affects various aspects of life and environment. One of the most common methods of drought assessing and monitoring is calculating drought indices (DIs). Drought areal and temporal extent and its ...
