Cyclonic circulation gives rain over Pakistan

Cyclonic circulation, prevailing over South Pakistan and south Iran, has given rain over southern parts of Pakistan and adjoining region of Iran. In a span of last 24 years, Jiwani recorded 55 mm of rain, Pasni 21 mm, Dalbandin 4 mm, Panjgur 2 mm, Khuzdar 1 mm and Karachi 0.2 mm.

In Iran, Saravan received 13 mm, Zahedan 4 mm, Zabol 3.6 mm and Bam 2.5 mm of rain.

According to Skymet Meteorology Division in India, the system has been induced by an active Western Disturbance, presently moving across northeast Afghanistan and north Pakistan. The system will continue to give rain during the next 24 hours as well.

Both the systems are moving in east direction towards India, where they are likely to affect weather from March 13 onwards. Western Disturbance would give widespread and heavy rain over Jammu and Kashmir along with other hilly states. While, cyclonic circulation will give rain over North Rajasthan and adjoining areas.

Western Disturbances aligned with induced cyclonic circulations become frequent during winters and are responsible for affecting the weather in the region to a large extent. This year, frequencies of these weather systems have increased, thus resulting in more amount of rain.

These systems after approaching the region usually stay for 1-2 days and give short spells of rain. The system is called Western Disturbance due to its movement from west to east.
