First, Empirical Orthogonal Function analysis method was applied for the monthly rainfall anomalies. A lot of rain (rainy season) falls in the month of: April, May, June, July, … Minor shifts of temperature through the year and high humidity create great weather conditions for vacations of all sorts. Nearby three quarters of Sri Lanka lies in what is widely known as the 'Dry Zone', comprising the northern half and the whole of the east of the country. The effect of climate variability on the rainfall pattern is canvassed on the Uma Oya river basin, Sri Lanka, consisting of 5 rainfall gauging stations. From the point of view of the spatial variation of rainfall, Sri Lanka is divided into wet, dry and inter-mediate zones (Thambyahpillay, 1954; Hunting Survey Corporation, 1963:7). It is located almost on the equator and have tropical monsoon climate. However, the Yala monsoon brings abundant rainfall to the southwest region from May to September, and to November in some coastal cities. The majority of water resources in Sri Lanka are generated by the hills in the central region which intercept the moisture-laden monsoonal winds from the south-west and north-east. The data consist of 55 years (1961–2015) of daily rainfall, maximum temperature ( T max ), and minimum temperature ( T min ) records from 20 stations scattered throughout Sri Lanka. The pattern of life in Sri Lanka depends directly on the availability of rainwater. In order to study the spatial and temporal patterns in Sri Lanka, monthly rainfall data at 29 stations for the period 1881–1980 were analysed in this study. Extreme weather events dominate the news but changing average weather patterns are proving equally devastating to poor and vulnerable people in climate hotspots across South Asia. Localized patches within the dryer areas of Sri Lanka shows increasing rainfalls but the general trend in the dryer area is a decreasing trend. Sri Lanka is an island country located in the northern Indian Ocean, southeast of India. Can anyone explain the rainfall patterns in Sri Lanka? Variation of Annual and Seasonal Rainfall Patterns in Kandy District of Sri Lanka U.S. Meegahakotuwa* and K.W.G.

An … Sri Lanka, formerly called "Ceylon", is an island nation in the Indian Ocean, southeast of the Indian subcontinent, in a strategic location near major Indian Ocean sea lanes.The nation has a total area of 65,610 km², with 62,705 km² of land and 2,905 km² of water. In this study, we used a comprehensive set of statistical metrics to investigate the historical trends in averages and extremes of rainfall and temperature in Sri Lanka. Monsoonal, Convectional and depressional rain accounts for a major share of the annual rainfall. (2003). Much of Sri Lanka receives 50% of its annual rainfall in the three months beginning October.
