This NIDIS-funded study, led by researchers at the University of Colorado Boulder/Cooperative Institute for Research in Environmental Sciences (CIRES), found that future hydrologic droughts are projected to become more severe and prolonged through the 21st century. This includes more frequent multi-year droughts. These storylines play out differently under different emissions scenarios, but seasonal shifts in drought timing were prominent in northern latitudes across all future scenarios.
Should drought be considered an extreme dry period based on the entire record of available data? Or, should drought be considered a low in precipitation variability within the context of a present, contemporary climate? The two most common reference periods are the full period of record (all observed data or as much as possible) and a 30-year reference climatology. However, climate non-stationarity may render the "all data" approach an inaccurate or obsolete comparison unless a trend is factored in.
From worsening water quality to respiratory and metal health impacts, drought can have profound and widespread impacts on the health of communities across the nation. To better prepare health professionals’ response to the health effects of drought, a research team from the University of Nebraska Medical Center’s College of Public Health recently released a new guide to assist healthcare providers and public health officials communicate about the health risks of drought with their patients and broader communities.
The National Integrated Drought Information System (NIDIS) is pleased to share our 2023 Annual Report to provide insight into the many accomplishments of the program over the previous year and the opportunities that lie ahead.
Quarterly Climate Impacts and Outlook for the Mid-Atlantic Region for December 2023–February 2024. Dated April 2024.
Average temperatures for the winter season were four to six degrees above normal for most of the region. The eastern portion of the region experienced wetter than normal conditions, up to 200 percent of normal precipitation.
Quarterly Climate Impacts and Outlook for the Midwest Region for December 2023–January 2024. Dated March 2024.
Winter temperatures were 4-8°F above normal across the lower Midwest and up to 12°Fabove normal across the upper Midwest. The Midwest, Iowa, Minnesota, Wisconsin, andMichigan had the warmest winter on record. Winter precipitation was near average for the Midwest, oscillating between wet and dry across the region from month to month. Minnesota had a record-wet December. Illinois had its second driest February.
Quarterly Climate Impacts and Outlook for the Southern Region for December 2023–February 2024. Dated March 2024.
Quarterly Climate Impacts and Outlook for the Great Lakes Region for December 2023–February 2024. Dated March 2024.
Winter was 2°C (4°F) to more than 6°C (11°F) above normal. The basin saw 78% of average precipitation for winter, with all basins but Ontario being dry.
Quarterly Climate Impacts and Outlook for the Gulf Coast Region for December 2023–February 2024. Dated March 2024.
Winter 2023-2024 temperatures were near normal across much of the Gulf Coast region, with temperatures averaging 2F below normal to 2F above normal in most locations. The Gulf Coast of Florida was the cool spot with most stations 2F below normal. Precipitation during winter 2023-2024 was variable across the Gulf Coast region.
Quarterly Climate Impacts and Outlook for the Missouri River Basin for December 2023–February 2024. Dated March 2024.
In typical El Niño fashion, temperatures were well above normal for the region. North Dakota recorded its warmest winter on record, while the majority of the region ranked in the top 5. Precipitation was above normal for the southern and eastern parts of the basin, while the northwestern portions were below normal.
