Analisis Profil Vertikal Parameter Meteorologi Daerah Troposfer Di Kototabang

Knowledge of the vertical structure of meteorology is important for understanding the atmosphere condition in the certain area, such as Sumatera which has specific topography. In this study was analyzed several meteorology parameter (pressure, temperature, relative humidity, titik embun temperature, and mixing ratio) retrieval radiosonda launching on December 2010. The object of this study is to find out the characteristic pattern of several meteorology parameters at Kototabang (0.20°S, 100.32°E). From the results show that for temperature from surface or about 10 m is 300 K then decrease up to 17 km, while there are inversion event at 250 m on average. This condition followed by decreasing of pressure are about 900 hPa at surface, decrease gradually up to 25 km, and after that the value near constant. Relative humidity at surface about (90-100)%, then decrease until reach (50-60)% at 250 m, after that fluctuating up down about (10-20)% at 17 km, furthermore the value decrease gradually. Decreasing of titik embun temperature on average almost the same which is occur on temperature, while titik embun temperature in the surface about 300 K, then decrease reach 17 km, furthermore increase about (10-20) K but not significantly. There is increasing the value of the titik embun temperature vertical profile at 250 m. Decreasing gradually of mixing ratio about 16 g/kg formerly at surface up to 1g/kg at 10 km
