Aerological climate of Xisha

The vertical distribution and seasonal variation of air temperature, humidity, static stability and Richardson number over Xisha Island are investigated based on 7-year records by means of time-altitude cross section, and harmonic and regression analyses. Mean data on height above sea level, air temperature, specific humidity, relative humidity and air density at standard-pressure surfaces are given respectively in terms of the annual average and the typhoon seasonal average of the South China Sea respectively.
