Description:
Clouds, convection and precipitation on Earth are organized in myriad ways: by variations in water vapor, by radiative feedbacks, by the circulations they inhabit. Their organization ranges from shallow cumuli excited around a cold pool, to hurricanes and basin-scale equatorial waves. This variability offers a lens through which to test the assumptions used in global climate and weather models.
In the NASA Global Modeling and Assimilation Office (GMAO) we develop the GEOS modeling system, used for near-real-time weather forecasts, seasonal prediction, and reanalysis production. Our tools include single column modeling, large eddy simulation, global cloud-resolving simulations, and a wide range of satellite observations. We invite applicants interested in all aspects of cloud, convection and precipitation variability, and their interaction with water vapor and other feedbacks.
Potential research topics include: cloud radiative feedbacks; convection or precipitation-humidity relationships; size distributions of precipitation or cloud features; convectively coupled equatorial waves or the MJO, including the influence of the maritime continent; gross moist stability or other cloud/convection diagnostics; and the diurnal cycle of convection.
