EIA for the proposed Hulhule-Male’ Bridge Project<br />

4.1.2 Winds<br />

The winds that occur across Maldives are mostly determined by the monsoon seasons. The two<br />

monsoons are considered mild given that Maldives is located close to the equator. As a result,<br />

strong winds and gales are infrequent although storms and line squalls can occur, usually in the<br />

period May to July. During stormy conditions gusts of up to 60 knots have been recorded at<br />

Male’.<br />

Wind has been uniform in speed and direction over the past twenty-plus monsoon seasons in the<br />

Maldives (Naseer, 2003). Wind speed is usually higher in central region of Maldives during both<br />

monsoons, with a maximum wind speed recorded at 18 ms-1 for the period 1975 to 2001. Mean<br />

wind speed as highest during the months May and October in the central region. Wind analysis<br />

indicates that the monsoon is considerably stronger in central and northern region of Maldives<br />

compared to the south (Naseer, 2003).<br />

Besides the annual monsoonal wind variations there are occasional tropical climatic disturbances<br />

(tropical storms or low intensity tropical cyclones) in the central region which increases wind<br />

speeds up to 110 km/h, precipitation to 30 to 40 cm over a 24 hour period and storm surges up to<br />

3 m in open ocean (UNDP, 2006).<br />

Table 4.2 summarises the wind conditions in central Maldives throughout a year. Medium term<br />

meteorological data from Hulhule Meteorological Centre (see Figure 4.2, Figure 4.3 and Figure<br />

4.4) and findings from long-term Comprehensive Ocean-Atmosphere Data Set (COADS) are<br />

used in this analysis.<br />
