Follow-up to Sep 2 and Sep 3 Dust and Flash Flood Concerns
Thursday, 3 September 2015
As mentioned in the previous post, we were concerned about the potential of organized thunderstorm outflow creating favorable conditions for blowing dust, as well as previous heavy rain activity increasing the potential for flash flooding in portions of Southeast Arizona yesterday (Sep 2) and today. We have been trying to use LIS data as part of our process in determining the threat of both of these problems. Yesterday was a mixed bag as I briefly outline below with less than full cooperation from the atmosphere.
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.

As part of its GOES-R Proving Ground activities, NASA SPoRT partners with NESDIS and Alaska weather forecast offices and river forecast center to assess the NESDIS Quantitative Precipitation Estimate (QPE) product at high latitudes. This image shows the 24 hour rainfall accumulation ending at 1200 UTC on 10 July 2014 over the Alaska domain.
