A Pareidolia Moment...
Wednesday, 19 August 2015
Yes, I'm just having one of those interesting moments, but cannot help from seeing the face in this picture. The Pacific is looking at us! This is a SPoRT-generated Airmass RGB from the Advanced Himawari Imager (AHI) aboard the recently launched Himawari satellite. SPoRT is generating some test imagery from the AHI, including several RGBs such as this Airmass RGB. By the way, that is Typhoon Goni on the left, approaching Taiwan, while Typhoon Atsani is farther to the east (on the right) and is currently forecast to track north of the Marianas Islands over the next few days.
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.

The Atmospheric Infrared Sounder (AIRS) ozone anomaly product valid at 2200 UTC on 27 February 2014. The blue region indicates ozone levels 125% of normal while the yellow region indicates >200% of normal ozone. The high concentrations of ozone help identify stratospheric air and potential vorticity, which can help identify the strength of an upper-level low.
