Indicators for the Compression and Stretching Characteristics of the HTF-Coordinate of WRF

Figure 3

The compression and stretahing of the vertical coordinate of the HTF-coordinate. The horizontal coordinate represents eta of the model and the vertical coordinate represents pd (ps = 600 hPa and pt = 10 hPa). (a) TF-coordinate. (b) HTF-coordinate and eta_c = 0.0. (c) HTF-coordinate and eta_c = 0.2. (d) HTF-coordinate and eta_c = 0.4.
