Suppiah, R. Spatial and temporal variations in the relationships between the Southern Oscillation phenomenon and the rainfall of Sri Lanka. Given the very large number of possible correlations, we just looked at total, number of rain days and number of days with ≥5 mm for OND and JFM, the seasons with the highest number of positive correlations (, Links between ENSO and Sri Lankan rainfall are now well established, including the detail of inter-seasonal variation (e.g., [, Results show that there are strong teleconnections for Sri Lankan rainfall with SSTs in the Pacific Ocean and, given the relative lack of significant correlations with IOD, these are apparently more important than SSTs in the Indian Ocean. Why you should get vaccinated. Rainfall over Sri Lanka is characterized by its tropical location and by the mon-soonal regime, and thus has a significant seasonal variation in the rainfall pat-tern. The Sri Lanka lowland rain forests represents Sri Lanka's Tropical rainforests below 1,000 m (3,281 ft) in elevation in the southwestern part of the island. Furthermore, the northward and southward migrations of the Inter Tropical Convergence Zone (ITCZ) during the year also govern the climate. The mean annual rainfall is less than 900mm in the South-eastern and north-western (driest) parts of the island to over 5000mm in the western slopes and the central highlands. Colombo receives rainfall from all three types of rainfall in Sri Lanka namely, Convectional, Monsoonal and Expressional.

Top luxury hotels in Sri Lanka . The mean precipitation of the year would be 6 mm (the rainfall of the whole area decreased in 2012) but the rainfall in certain cells (certain areas) actually increased (1 mm versus 20 mm). Modulation of Sri Lanka’s climate during El Niño events is related to changes in the Walker circulation, resulting in heightened convection over Sri Lanka in OND and enhanced subsidence during the rest of the year [, We have not investigated links with SSTs in the Bay of Bengal but judging by results in [, Other than OND, significant correlations are almost all negative (JAS, JFM, M+A) or not found at all (AMJ). The monsoonal rainfall is categorized into 4 main types according to the direction of wind flow. Rainfall indices tend to be much better correlated with climatic drivers during the two monsoon season than in the inter-monsoon periods, particularly at the stations with higher seasonal totals. Precipitation in Sri Lanka averaged 142.05 mm from 1901 until 2015, reaching an all time high of 687.50 mm in December of 1957 and a record low of 1.20 mm in February of 1980.
