Research results relevant to the analysis and prediction of observed atmospheric circulations and physics, including technique development, data assimilation, model validation, and relevant case studies. This includes papers on numerical and data assimilation techniques that apply to the atmosphere and/or ocean environments as well as socioeconomic analyses of the impacts of weather and weather forecasts. MWR focuses on phenomena having seasonal and subseasonal time scales. Reviews of climatological aspects of high-impact events such as hurricanes, as well as review articles, are occasionally published.
New map of the UK pinpoints tornado hotspots for the first time in two decades
Researchers have updated a map of the UK that pinpoints tornado hotspots for the first time in two decades.
Powerful pressure systems may stir desert sand storms
Strong pressure systems a third of a world apart may set up conditions to stir powerful summer dust storms over the Arabian Peninsula.
Research offers new way to predict hurricane strength, destruction
A new study by Florida State University researchers demonstrates a different way of projecting a hurricane's strength and intensity that could give the public a better idea of a storm's potential for destruction.
Multiple consecutive days of tornado activity spawn worst events
Significant tornado outbreaks and especially strong tornadoes are more likely occur within periods of activity lasting three or more days, according to a Purdue University tornado expert.
Student studies dry lines in Southeastern Wyoming
In southeastern Wyoming, people are more than ready this time of year to get outside and enjoy the warmer weather. Then, suddenly, they feel the wind pick up and the temperatures cool ‑‑ signs of an impending thunderstorm.
NASA sees super-rapid intensification of Supertyphoon Usagi
The radar on the Tropical Rainfall Measuring Mission (TRMM) satellite captured an image of Supertyphoon Usagi near the end of a 24-hour period in which Usagi intensified by 65 knots. This is more than twice ...
Ahoy aquaplanet: Identifying model resolution shortcomings
By putting models through their paces in an all-water world, scientists at Pacific Northwest National Laboratory found highly scale-sensitive issues in regional climate modeling. In the first of two studies, ...
Researchers develop new metric to measure destructive potential of hurricanes
Researchers at Florida State University have developed a new metric to measure seasonal Atlantic tropical cyclone activity that focuses on the size of storms in addition to the duration and intensity, a measure that may prove ...
Lake-effect snow sometimes needs mountains
University of Utah researchers ran computer simulations to show that the snow-producing "lake effect" isn't always enough to cause heavy snowfall, but that mountains or other surrounding topography sometimes ...
