Understanding and Modeling the Tropical Atmosphere: Phenomena, Processes and Resolution
Richard Neale (NCAR)
November 4, 2010
Techniques for representing convective processes in global models are in a transitional phase. Existing assumptions for parameterizing convection are increasingly inadequate due to ever finer horizontal grids and increasing demands on th...
Tropical squall lines and convectively coupled gravity waves: Why do most cloud systems move westward?
Stefan Tulich (NOAA)
October 28, 2010
The existence of tropical squall line systems has been recognized for quite some time, yet their governing dynamics still remains unclear. Here it is proposed that many tropical squall lines are part of a broad family of convectively cou...
GOES-R Overview of Aviation and Nowcasting Applications - Current status and a look into the future
Wayne Feltz (UW-Madison)
October 21, 2010
The NOAA GOES-R Aviation Algorithm Working Group was formed in November 2006 to assess satisfying aviation related requirements as defined in the GOES-R Mission Requirements Document. A suite of aviation related products are in developme...
Member selection for a convective scale ensemble at the UK Met Office
Geovanni Leoncini (U.K. Met Office)
October 6, 2010
The UK Met Office is developing an ensemble at the convective scale by embedding the new 1.5km model over the UK within selected members of the regional scale ensemble MOGREPS-R (~18km covering the North Atlantic and Western Europe). The...
My Visit to the Dark Side: Engaging Climate Change Denial
Scott Denning (CSU)
September 30, 2010
Global climate change is no longer merely a scientific field of study but has emerged as a major issue in American popular culture and political discourse. The treatment of climate and global change is therefore now treated to political ...
Measuring Fluxes of Ammonia and Other Trace Gases Using Eddy Covariance and Relaxed Eddy Accumulation
Jay Ham (CSU Crop and Soil Sciences)
September 23, 2010
“when you cannot measure it, ..., your knowledge is of a meagre and unsatisfactory kind”
-- William Thomson Kelvin, 1883
Measurement of energy and mass exchange in the surface boundary layer is fundamental to ...
The Impact of North Pacific Atmospheric Variability on ENSO via the "Seasonal Footprinting Mechanism"
Mike Alexander (NOAA)
September 16, 2010
Previous studies suggest that the â€œseasonal footprinting mechanismâ€ (SFM), in which fluctuations in the North Pacific Oscillation (NPO), a north south dipole in the sea level pressure pattern influence the ocean. NPO-related ...
Simulation of the Asian Monsoon in a Super-parametrized AOGCM
Charlotte DeMott (CSU)
September 9, 2010
Climate simulations using a multi-scale modeling framework (MMF), or â€œsuper- parameterizationâ€ may offer new insights into the role of convection, air-sea coupling, and equatorially-trapped waves on the simulation of the Asia...
Acceleration of the Brewer-Dobson Circulation in a Changing Climate
Rolando Garcia (NCAR)
September 2, 2010
National Center for Atmospheric Research, Boulder, CO, USA
The evolution of the Brewer-Dobson (BD) circulation as a result of climate change has been analyzed using NCARâ€™s Whole Atmosphere Community Climate Model (WACCM). Two e...
