How Land-Atmosphere Interactions Magnified the Drought and Heatwave over Northern Europe during Summer 2018

During the summer of 2018, Northern Europe experienced a devastating heatwave and drought; with unprecedented forest fires in Sweden, excessive heat in Germany, and water restrictions in England, these events had far-reaching economic and ecological impacts.

ENSO Teleconnections and Impacts During U.S. Summertime 8 May 2020

ENSO Teleconnections and Impacts During U.S. Summertime

The El Niño-Southern Oscillation (ENSO) is a phenomenon where atmosphere and ocean dynamics couple to change the temperature of waters in the central and eastern Pacific Ocean, the circulation of the tropical atmosphere, and the global atmospheric circulation. A new study sheds light on ENSO teleconnections and impacts on U.S. summertime.

Can We Expect More Extratropical Transitions in a Warming Climate? 17 April 2020

Can We Expect More Extratropical Transitions in a Warming Climate?

During this transformation, a cyclone's wind and precipitation area increases in size, and the storm may produce large waves and swell as it accelerates forward, which are important changes to understand and predict for risk assessment

Is There a Connection Between MJO and Tornadoes in the United States? 2 April 2020

Is There a Connection Between MJO and Tornadoes in the United States?

With the United States experiencing the largest number of annual tornado events of any country, it’s critical for atmospheric studies to continue to enhance tornado outlooks and projections for our country. New research accepted for publication, funded by the MAPP Program, shows that different phases of the Madden-Julian Oscillation’s (MJO) — an eastward moving tropical rainfall pattern — global trek can produce more or less favorable conditions for U.S. tornado activity.

The South Asian Summer Monsoon: What Our Climate Projections Tell Us 23 March 2020

The South Asian Summer Monsoon: What Our Climate Projections Tell Us

A paper just published in Science Advances, funded by the MAPP Program, identified a key climate pattern responsible, in part, for large uncertainties in projections of the South Asian summer monsoon (SASM). The SASM is the strongest component of the global monsoon system and contributes about 80% of South Asia’s annual rainfall and provides the water supply for more than a billion people.
