Modeling the combined environmental effects on net land carbon flux in the present and future scenarios (2020-05-14)Anthropogenic activities such as fossil fuel production and Land Use and Land Use Changes (LULCC) have been contributing to the sources for the atmospheric carbon dioxide (CO2) in the global carbon cycle. The terrestrial ...
Cloud top phase characterization of cold sector Southern Ocean clouds and ice production at warm cloud top temperatures: results from the SOCRATES field campaign (2020-05-14)Low-level cloud cover over the Southern Ocean (SO) has a significant influence on global radiative balance. Climate models have had difficulty in the past reproducing shortwave radiation reflected by these clouds because ...
Analyses of quasi-linear convective system tornado characteristics, environments, and genesis mechanisms (2020-05-13)The primary goal of this research was to quantify occurrence frequencies of the two main proposed mechanisms of tornadogenesis in quasi-linear convective systems (QLCSs), namely, tilting and stretching (T&S) and HSI and ...
The observed relationship between tornado intensity and pretornadic mesocyclone characteristics and environments (2020-05-05)Trapp et al. (2017, JAS) used idealized model simulations of supercell thunderstorms to demonstrate support of their hypothesis that wide, intense tornadoes should form more readily out of wide, rotating updrafts. ...
High resolution numerical simulation of a nocturnal mesoscale convective system: Comparison with pecan observations (2020-04-30)Nighttime convective storms produce a significant portion of warm season precipitation across the Great Plains region of the United States. The PECAN (Plains Elevated Convection at Night) project was designed to improve ...
