TWP-ICE/ACTIVE MONSOON CASE STUDY

Apparent heating rate and moisture sink profiles from variational analysis (white symbols) versus sample case study simulations (colored symbols):





Comments:

• Mean profiles are calculated for six 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 three are sequential monsoon events of varying intensity.
• Forcing data set derived from variational analysis over the TWP-ICE domain bounded by sounding sites, provided by Shaocheng Xie and Minghua Zhang (summary with download link), reported as 3-hr mean values over the 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 instantaneous values reported at 3-hr frequency and 1-km resolution over a domain size of about 37,000 km². Mean values are shown at each level for each time period.

Preliminary summary:

• Reasonable agreement throughout. Model values exceed forcing values significantly aloft during event C.
