(d) WCB trajectories are as in (c), but from a different viewpoint and combined with a cross section showing 3D WCB probabilities (color shading; %), ensemble-mean potential temperature (black contours; K), and the 2-PVU isoline (red contour), (e) COAMPS adjoint 48-h forecast moisture sensitivity at 850 hPa [color shading; increments every 0.2 [m.sup.2] [s.sup.-2] [(g [kg.sup.-1]).sup.-1]] and 850-hPa geopotential heights (contours every 30 m) valid at 1200 UTC 24 Sep (initial forecast time).
The COAMPS results (bottom row) reveal the presence of low-level cool and moist air and the dry layer above 1,300 m, in good agreement with the rawinsonde profiles.
A comparison between the M field computed from the TO measurements and the soundings reveals the finescale structure of the modified refractivity in the aircraft measurements that are not present in the five soundings along the path or the COAMPS results.
The forecasts were compared with the model itself as well as with some external models --deterministic global pressure and temperature (GPT2) model and numerical weather prediction model COAMPS (Coupled Ocean/Atmosphere Mesoscale Prediction System).
COAMPS TC is the latest advancement in weather models for tropical cyclone predictions.
The analysis of the flow derived from radio sounding and NWP COAMPS model, shows that the actual correlation between consecutive voxels in the model is weaker in the bottom part and grows with increasing height.
These programs use data from the COAMPS model run on IA64 Feniks computer cluster in the Department of Civil Engineering and Geodesy of the Military University of Technology.

The model choices for the mesoscale are WRF and Coupled Ocean-Atmosphere Mesoscale Prediction System (COAMPS), but the focus hitherto has been on WRF, approaching from multiple angles using complementary efforts.
