Climate & Weather `Low pressure' in Bay of Bengal Our Bureau
THE upper air cyclonic circulation that has been persisting over Southeast and adjoining Southwest Bay of Bengal has set up a low-pressure area over the Southeast Bay on Friday. According to the official India Meteorological Department (IMD) forecast, the associated upper air cyclonic circulation has been found to extend up to 3.1 km above sea level. The system is likely to become more marked over time. Under its influence rain/thundershowers are likely at many places over Andaman and Nicobar islands and isolated in Andhra Pradesh, Tamil Nadu and Pondicherry. Kerala weather: In Kerala, the productive session with the summer showers continued, though in varying scales, as rainfall recorded turned out to be `in excess' in 10 districts; `normal' in two; `deficient' in one; and `scanty' in another during the season starting March 2005. According to the Agromet Bulletin dated May 5 issued by the Met Office here, Kannur in the north (+248 per cent)) was the spectacular gainer among districts recording `excess' rainfall. Strangely enough, Kasaragode (-29) and Kozhikode (-60) districts that share borders with it in the north and south ended up in the `deficient' and `scanty' categories. Ernakulam (+11) and Malappuram (-13) fell under the `normal' category, falling as they did within the `20 per cent median' on either side. Those joining Kannur in the `excess' category (in percentage figures) included Thiruvananthapuram (+116); Idukki (+74); Palakkad (+65); Pathanamthitta (+56); Wayanad (+44); Kottayam (+41); Thrissur (+39); Alappuzha (+37) and Kollam (+26). Chief amounts of rainfall in cm are (May 2 to May 4): May 2: Aryankavu - 3 May 3: Thodupuzha and Neyyattinkara - 7 each; Thiruvananthapuram - 4; Thiruvananthapuram Airport, Kanjirappally and Varkala - 3 each; and Mavelikkara, Aluva and Thiruvalla - 2 each. May 4: Alappuzha - 1. Mean maximum temperature varied between 33°C and 35°C in various districts. Kannur recorded the highest maximum of 35.6°C on May 3. The maximum was 3°C above normal in Thiruvananthapuram on May 2. Mean relative humidity varied between 67 per cent and 83 per cent, mean cloud coverage between 4 okta and 8 okta and mean wind speed, 2 kmph and 8 kmph. Forecast valid until the morning May 7 spoke about the possibility of rain/thundershowers in all districts. Outlook for the two subsequent days did not indicate any change.
