Spatial distribution of two widespread precipitation events that occurred on 8 May 1995 and 13 September 1961 and geometric illustration of the extent of an SHPE on the ground.
December 30, 2020

Najibi, Devineni, and co-authors present a new idea defined as simultaneous heavy precipitation events (SHPEs) to quantify extreme regional precipitation considering the spatial structure of extreme events. Quantifying the characteristics of SHPEs and modeling their footprints can improve the projections of flood risk and understanding of damages to interconnected infrastructure systems.

Hurricane Harvey and Louisiana flood
June 18, 2018

Regional model simulations suggest that post-1980 warming in both the ocean and atmosphere resulted in an estimated 20% increase of the accumulated precipitation for Hurricane Harvey.

Research shows that SST may explain a significantly smaller percentage of the variance in tropical cyclone intensification in the Atlantic as compared to the western North Pacific and eastern-central Pacific.

Atlantic hurricanes
December 11, 2017

Using observations and a coupled Earth system model, a new study shows that the decline of the Atlantic major hurricane frequency during 2005–2015 is associated with a weakening of the AMOC.

Buoyancy frequencies

A recent study highlights results obtained from an aircraft ocean survey that targeted a large warm core eddy in the eastern Caribbean Sea, where upper ocean measurements are crucial to understanding the complexities of heat and moisture transfer during the passage of tropical cyclones.

Hurricanes more likely to weaken along the US coast during active periods
January 6, 2017

A new study shows that when conditions in the deep tropics are good for hurricane intensification, they are bad along the US coast. This sets up a barrier around the US coast during active hurricane periods that inhibits hurricanes from strengthening and usually causes them to weaken.

El Nino events and tropical cyclones, models compared to observations
September 7, 2016

It is well known that ENSO strongly affects the interannual variability of tropical cyclones in the western North Pacific. New research shows that models can reproduce interannual variability, but none can capture the distinction between eastern Pacific and central Pacific El Niño events that is found in observations.

Hurricane frequency in model runs
February 2, 2015

Climate extremes such as hurricanes and typhoons can cause death and destruction for communities around the world. Scientists are interested in studying both the predictability and possible future changes in the frequency and intensity of such storms.

Hurricane storm track
January 22, 2015

Tropical cyclones are among the most devastating storms on Earth. Tropical cyclone activity in the North Atlantic displays large interannual variability in both number and track density. Recent studies show that global high-resolution models have remarkable skill in simulating the interannual variability in cyclone counts, implicating strong control by sea surface temperatures patterns.
