low CAPE values over Kuala Lumpur

By: 0122855600 , 6:17 AM GMT on January 16, 2014

Apperently the reason why yesterdays showers over Kuala Lumpur, did not develop into thunderstorms was the low CAPE(convective available potential energy) values.In fact the prediction of low CAPE values by weather models had caused many meteorologists to forecast no rain in Kuala Lumpur yesterday.The showers formed as a result of the afternoon southwesterly sea breeze converging with the northeasterly winds.Many meteorologists did not expect the wind convergence to bring any rain to Kuala Lumpur yesterday as the northeasterly winds were also rather dry as indicated by the minimum dew point temperature of 20 Degrees Celsius yesterday at the Sultan Abdul Aziz Shah Airport which was the lowest recorded since September 29 2013.

KLIA also recorded rather low dew point temperatures of 20 Degrees Celsius Yesterday and on Tuesday which was the lowest since August 4 2013.

The relatively low dew point temperature also caused cooler nights as the dew point temperature indicates the temperature to which the water vapour in the air must be cooled to in order to condense to form dew.

When the water vapour condenses to form dew it releases latent heat of condensation into the air which prevents the temperature from dropping further.

Good morning.

It has been really cool outside today, by Malaysian standards of course.
