Abstract
A research has been conducted on analysis of above air weather elements with the
potential energy of convective activity (CAPE) to determine the rainfall prediction
desert in Padang city. Convection process is an important role in the transfer and
distribution of mass and energy in the medium of the atmosphere. The method used in
this research is statistical correlation and Student T test. The data used are secondary
data obtained from Meteorological and Geophysics Board at airport Sultan Syarif
Kasim II Pekanbaru Riau. From the analysis it can be seen a strong relevance among
temperature, relative humidity, dew point, wind speed and rain the against convection
process. This correlation indicates a presence of a strong relevance among air weather variables with CAPE value of > 0,5. After the Student T test it showed that the
influence of the CAPE variables has the same average value. The value CAPE of variables temperature in the rainy season in January 2012 is -3.710 and -5.508 in the dry
season in July 2012 with the values t table of 1.699 then Ho is accepted.
