SPoRT Science Seminar Series
SPoRT periodically hosts visitors to learn more about our program and team as well as to discuss opportunities for future collaboration. Typically, during these visits, the guest will present a seminar outlining his or her current work to help provide background on common interests. Please check back soon for information on the next seminar.

NtMicro RGB: Fog vs Stratus
Tue, 28 Mar 2017 22:22:44
A veritable buffet of things to digest are occurring in this Nighttime Microphysics RGB animation from 0600 to 1000 UTC in the early morning of 3/28/17 where multi-state impacts of stratus and fog are seen (Fig 1). In blue/aqua to gray shades, the low cloud features are developingover the central CONUS while being sandwiched between [...]
Improving the representation of snow crystal properties within a single-moment microphysics scheme
Single-moment microphysics schemes are utilized in an increasing number of applications and are widely available within numerical modeling packages, often executed in near real-time to aid in the issuance of weather forecasts and advisories. In order to simulate cloud microphysical and precipitation processes, a number of assumptions are made within these schemes. Snow crystals are often assumed to be spherical and of uniform density, and their size distribution intercept may be fixed to simplify calculation of the remaining parameters.

This MODIS snow/cloud RGB composite is used to distinguish between cloud cover (white), clear ground (green), and snow cover (red). This image from 8 March 2008 shows the extent of snow cover from Arkansas, most of Tennessee, and into Kentucky and shows that northern Alabama did not accumulate any snowfall.
