Elevation of Central American orography significantly reduces the pervasive tropical rainfall bias by blocking the easterlies and consequently warming the northeastern tropical Pacific.
New insights from observations and theory suggest that the essential drivers of Earth’s summer monsoons are not as obvious as was previously thought.
Both satellite observations and model simulations reveal that more aggregated convection amplifies the increase in extreme rainfall events on a year-to-year basis.
Understanding the fundamental physics of the Madden‐Julian Oscillation, a phenomenon that occurs over the Indian and Pacific Oceans, remains a challenge in tropical atmospheric research.
A new conceptual framework on how convection works in the tropics helps advance understanding of the contrast between land and ocean and how the tropics will respond to climate change.
A new mechanism explains changes in the probability distribution of tropical rainfall, which is not expected to change uniformly in a warming climate.
Unique observations used to examine the structure and mass balance of hurricanes’ top levels find that regions of high pressure violate the gradient wind balance.
El Niño events have significant global impacts on weather and climate, but these reach up into the stratosphere, beyond the troposphere where most of Earth’s weather takes place.
Joint SPARC Dynamics and Observations Workshop; Kyoto, Japan, 9–14 October 2017
In the Stratéole 2 program, set to launch in November 2018, instruments will ride balloons into the stratosphere and circle the world, observing properties of the air and winds in fine detail.
