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
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.
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.
Despite major progress in monitoring and understanding the El Nino-Southern Oscillation (ENSO), an alternating climate pattern of abnormally warm and cool ocean temperatures across the tropical Pacific, scientists’ ability to predict it has not shown steady improvement over the past few decades. Helping to solve this mystery, a new review article funded by the MAPP Program found that a shift in ENSO properties around 1999/2000 may account for the lower prediction skill.
Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather.
