Coates, David A (2021-04-28)Moist processes can produce kinetic energy at subsynoptic scales, traditionally regarded as part of the -5/3 inertial subrange. Atmospheric kinetic energy cascades to both smaller and larger scales, so moist dynamics at ...

Patil, Sandeep 1986- (2013-01-14)Meteorological drought indices are commonly calculated from climatic stations that have long-term historical data and then converted to a regular grid using spatial interpolation methods. The gridded drought indices are ...

Hoerling, Martin; Kumar, Arun; Dole, Randall; Nielsen-Gammon, John; Eischeid, Jon; Perlwitz, Judith; Quan, Xiao-Wei; Zhang, Tao; Pegion, Philip; Chen, Mingyue (American Meteorological Society, 2013-04-26)The record-setting 2011 Texas drought/heat wave is examined to identify physical processes, underlying causes, and predictability. October 2010–September 2011 was Texas’s driest 12-month period on record. While the summer ...

Smith, Jamie Brooke (Texas A&M University, 2006-08-16)The baroclinic and surface-frictional contributions to stratified wake formation are considered as a function of the non-dimensional height ( = Nho/U) and aspect-ratio ( = ho/L) of the barrier. Numerical simulations are ...

Livingston, Eric; Nielsen-Gammon, John; Orville, Richard (American Meteorological Society, 1996-07-01)A lightning climatology within 50 km of nine outdoor venue locations for the 1996 Summer Olympics has been produced. Spatial and temporal patterns were analyzed for July and August from 1986 through 1993. Unusually active ...

Nielsen-Gammon, John; Schultz, David (American Meteorological Society, 1999-09-01)The recent article by Chen et al. (1998; henceforth Chen) concludes that three processes were important to the development of a particular low-level jet (LLJ) associated with a mei-yu front: (1) a transverse circulation ...

Myoung, Boksoon; Nielsen-Gammon, John (American Meteorological Society, 2010-09-01)This research is designed to investigate how convective instability influences monthly mean precipitation in Texas in the summertime and to examine the modulation of convective instability and precipitation by local and ...
-
Myoung, Boksoon; Nielsen-Gammon, John (American Meteorological Society, 2010-09-01)This study is concerned with the modulation by convective instability of summertime precipitation in Texas as a mechanism for maintaining or enhancing drought. The important role of convective inhibition (CIN), its dependence ...

Nielsen-Gammon, John; Read, William (American Meteorological Society, 1995-03-01)Left-moving supercells, which rotate anticyclonically, are much less common than their right-moving counterparts but are nevertheless capable of producing severe weather. On 26 May 1992, a severe left-moving thunderstorm ...

Pielke, Roger Sr; Nielsen-Gammon, John; Davey, Christopher; Angel, Jim; Bliss, Odie; Doesken, Nolan; Cai, Ming; Fall, Souleymane; Niyogi, Dev; Gallo, Kevin; Hale, Robert; Hubbard, Kenneth; Lin, Xiaomao; Li, Hong; Raman, Sethu (2016-10-28)The objective of this research is to determine whether poorly sited long-term surface temperature monitoring sites have been adjusted in order to provide spatially representative independent data for use in regional and ...
-
Nielsen-Gammon, John; Keyser, Daniel (American Meteorological Society, 2000-08-01)Effective stratification can be interpreted as the resistance to upward motion of saturated air parcels experiencing condensation. Previously published expressions for effective stratification conflict with each other, and ...
