TWP-ICE/ACTIVE MONSOON CASE STUDY

Reflectivity frequencies based on measurements (white symbols) versus sample case study simulations (colored lines):







Comments:

• Mean and maximum profiles are calculated for nine time ranges. The first three are longer time ranges: (1) all times following an initial 36 hours for model spin-up, (2) six days of monsoon, and (3) six days of suppressed conditions. The second six are 24-hour periods: three sequential monsoon events of increasing intensity, followed by cirrus evolution after the third event.
• Reflectivities from the C-Pol radar at Darwin are supplied by the Peter May and the Australian Bureau of Meteorology. Retrievals represent instantaneous values reported at 10-min and 1-km vertical and horizontal resolution over an area of approximately 25,000 km².
• All measurement data have been downloaded from the DOE ARM data archive (www.arm.gov) and use in publications is subject to the policies described there. Any errors in plotting or representation shown here should be blamed on Ann Fridlind.
• Model results are derived from fields reported at 3-hr frequency and 1-km resolution with a domain size of about 37,000 km².

Preliminary summary:

• Radar and model results (derived from bulk microphysics assumptions) require additional evaluation.
