RISThe Ensemble Tangent Linear Model Applied to Nonorographic Gravity Wave Drag
Publisher: American Meteorological Society
Smoke With Induced Rotation and Lofting (SWIRL) in the Stratosphere
Publisher: American Meteorological Society
Abstract: The Australian bushfires of 2019/20 produced an unusually large number of pyrocumulonimbus (pyroCb) that injected huge amounts of smoke into the lower stratosphere. The pyroCbs from 29 December - 4 January were particularly ...
Interannual Changes of Stratospheric Water Vapor and Correlations with Tropical Tropopause Temperatures
Publisher: American Meteorological Society
Abstract: Interannual variations of stratospheric water vapor over 1992?2003 are studied using Halogen Occultation Experiment (HALOE) satellite measurements. Interannual anomalies in water vapor with an approximate 2-yr periodicity ...

Hybrid 4DVAR with a Local Ensemble Tangent Linear Model: Application to the Shallow-Water Model
Publisher: American Meteorological Society
Abstract: n ensemble-based tangent linear model (TLM) is described and tested in data assimilation experiments using a global shallow-water model (SWM). A hybrid variational data assimilation system was developed with a 4D variational ...
Evaluation of SSMIS Upper Atmosphere Sounding Channels for High-Altitude Data Assimilation
Publisher: American Meteorological Society
Abstract: pper atmosphere sounding (UAS) channels of the Special Sensor Microwave Imager/Sounder (SSMIS) were assimilated using a high-altitude version of the Navy Global Environmental Model (NAVGEM) in order to investigate their ...
