Study Finds that a Larger than Normal Atlantic Warm Pool Can Lead to an Increase in US Heat Waves

Heat extremes are the number one weather-related cause of death in the United States, prompting the climate community to study the driving forces behind these extreme events to improve their prediction. A new study published in the Journal of Geophysical Research finds an increase in summertime heat wave occurrence over the US Great Plains is linked to a larger than normal tropical Atlantic warm pool.

NOAA AOML Scientists Project Future Changes in ENSO Variability

In a new study published in Nature Communications, scientists at NOAA’s Atlantic Oceanographic & Meteorological Laboratory (AOML) investigate the projected changes in the seasonal evolution of El Niño – Southern Oscillation (ENSO) in the 21st century under the influence of increasing greenhouse gases. The study found that global climate impacts on temperature and precipitation are projected to become more significant and persistent, due to the larger amplitude and extended persistence of El Niño in the second half of the 21st Century (2051-2100).

AOML Scientists Tackle one of the Most Challenging Problems in U.S. Seasonal Rainfall Prediction

In a recent article published in Geophysical Research Letters, AOML and CIMAS scientists investigated U.S. rainfall variability, focusing on the late summer to mid-fall (August-October) season. The main goal of the study was to identify potential predictors of U.S. precipitation during August-October and to explore the underlying physical mechanisms.

Connection between Madden-Julian Oscillation and U.S Tornadoes may Provide Earlier Warning for Storms

Recently, scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) and the Cooperative Institute for Marine and Atmospheric Studies (CIMAS) explored the physical causes between U.S. tornado activity and the Madden-Julian Oscillation. In a study recently published in the Journal of Climate (Kim et al., 2020), they showed that a series of key atmosphere-ocean processes are involved in the remote impact of Madden-Julian Oscillation on U.S. tornado activity.
