- 90 - on the beau fort scale. However the surface winds are generally light and variable during late night/early morning hours. 35. Cyclonic Storms I Depressions. Other than October and November (Post Monsoon Period) the month of May (Pre Monsoon Season) is the period of the cyclonic activity. The whole of Bay of Bengal to the North of 10 degree is susceptible to the formation of depressions. The depressions storms which form in the later part of this month at times are responsible for the advancement of SW Monsoon over the Indian pennisu1a earlier than schedule. The depressions / storms of the pre-monsoon season generally form in situ in the Indian sea areas. These systems form when the East West oriented trough intensifies. The frequency of formation of Cyclone Storms, Severe Cyclonic Storms and Depression per year is .48, .40 and .64respectively. They move in NW /NHWly direction and later on recurve in NJE direction. The system generally does not recurve when it is west of 85 degree East. 36. Thunder Storm Activity. Due to intense heating over land and presence of anticyclone over control Bay during the month, the thunder storm activity reaches its peak in the month of May over the entire East Coast. (a) Areas of Thunderstorm Activity. The areas of Occurrence of thunder activity during the month of May remain the same as in the month of April, Viz. Gangetic West Bengal, Bihar, Orissa, Assam and adjoining states in the WE India, Madhya Pradesh, Vidarbha in the central parts of the country and Kerala, Karnataka and Tamil Nadu in the southern peninsula. It also occurs though with a low frequency, in the coastal areas of Andhra Pradesh. (b) Frequency. Thunder Storm activity in Assam and adjoining areas and Kerala may be as high as 14-16 days during the month of May. The number of Thunder activity over Coastal Andhra Pradesh is 7-8 days during this month. 37. Heat Waves. The significant departures of temperatures above normal causes hot weather spells, which are also termed as Heat Waves. They generally occurs during the later part of the hot weather period as well as the during the month of June and July in some parts of the country. (a) Classification. The heat waves are classified based on the departure of the maximum temperature above the normal values. If the
- 91 - maximum temperature is 6ْ Deg C to 7ْDeg C above normal it is termed as Moderate Heat Wave. If the maximum temperatures is 8ْ degree Celsius on more above normal, it is known as Serve Heat Wave. (b) Areas of Occurrence. The heat wave generally occurs in north India and even the interior areas mostly come under the grip of heat waves. The coastal areas, J & K East up East Madhya Pradesh, Punjab, Haryana and Bihar are the most favorable regions for the occurrence of the heat waves every year. Lakshadweep Bay Islands, Kerala Coastal Karnataka are generally not affected by heat wave. (c) Frequency. The Frequency of heat waves is maximum. During the month of June, but it is quite significant in the month of May too. While 54% of heat waves occur in June, their frequency is only 10% during the month of May. During the period from 1911 to 1967, the coastal areas of Andhra Pradesh experienced 4 and 13 severe heat waves during the month of May and June respectively. As the SW Monsoon advances, the activity of heat waves also shifts from eastern to western part of the country. d) Duration. The normal duration of heat waves over the country is not more than 4-5 days, but they may not last for more than 1 or 2 days in a region. However the only exception is the Bihar Plateau where sever heat wave may last as long 4 to 5 days. 38. General Weather Summary. May is the hottest month of the year along the whole of the East Coast of India and the highest day temperatures are recorded in may parts of the country during the month. Consequently the heat waves sweep over many parts of India, including coastal Andhra Pradesh. Weather is generally fair becomes cloudy towards evening. The clouds during the month of May are generally of cumulus type; develop into the thunder clouds (CB) by afternoon/evening hours. The rainfall which occurs in association with the thunderstorms activity is generally isolated/scattered over the area. 39. Currents Off East Coast. The general Pattern of currents over Bay of Bengal during the month of May is influenced by setting in and strengthening of SWly winds. The surface water current in May mainly follow NE-ENEly direction the average speeds of the currents are 0.5 and 0.75. in the open sea, the

35. Cyclonic Storms I Depressions. Other than October and November<br />
(Post Monsoon Period) the month of May (Pre Monsoon Season) is the period of<br />
the cyclonic activity. The whole of Bay of Bengal to the North of 10 degree is<br />

frequency of formation of Cyclone Storms, Severe Cyclonic Storms and<br />
Depression per year is .48, .40 and .64respectively. They move in NW /NHWly<br />

recurve when it is west of 85 degree East.<br />
36. Thunder Storm Activity. Due to intense heating over land and<br />
presence of anticyclone over control Bay during the month, the thunder storm<br />
activity reaches its peak in the month of May over the entire East <strong>Coast</strong>.<br />
(a) Areas of Thunderstorm Activity. The areas of Occurrence of<br />
thunder activity during the month of May remain the same as in the month<br />
of April, Viz. Gangetic West Bengal, Bihar, Orissa, Assam and adjoining<br />
states in the WE India, Madhya Pradesh, Vidarbha in the central parts of<br />
the country and Kerala, Karnataka and Tamil Nadu in the southern<br />
peninsula. It also occurs though with a low frequency, in the coastal areas<br />
of Andhra Pradesh.<br />
(b) Frequency. Thunder Storm activity in Assam and adjoining areas<br />
and Kerala may be as high as 14-16 days during the month of May. The<br />
number of Thunder activity over <strong>Coast</strong>al Andhra Pradesh is 7-8 days<br />
during this month.<br />
