Fig.m8 Cross section for CCV, CLW, relative humidity(RH), CCV computed using Randal formula (CCV_R), zonal wind (U), and meridional wind (V) and . Values are averaged between 138E and 140E. Name of the values are indicated as subtitle. Contour intervals are 20% for CCV, 50x10-6 Kg/Kg for CLW, 10% for RH, 20% for CCV, 5ms-1 for zonal wind. Factor 100 is multiplied to to plot with meridional wind V. Fig.m9 Time -latitude section of zonally averaged nature run HCC. Fig.m10 Zonally averaged cloud cover from NCEP analysis.
