(within 1 km of the coast), Sri Lanka’s coastal zones face serious threat from sea-level rise caused by climate change, which could amplify existing hazards from tsunamis and cyclones. The Sri Lankan Relict Ant in Aneuretinae has many records in the wet zone and two records in the intermediate zone. Sri Lanka. Sri Lanka is characterized by well-demarcated climatic zones based on the rainfall pattern known as wet zone, dry zone and intermediate zone. The longest river of Sri Lanka is the Mahaweli Ganga with its length of 335 kilometers. Samples were collected representing all the agro-climatic zones in Sri Lanka according to the availability. The average annual temperature is 27.0 °C | 80.6 °F in Colombo. The country is located just north of the equator. I focus here on the OSFs of the Wet Zone because Sri Lanka’s rich and fascinating endemic biota (fauna and flora) is overwhelmingly concentrated in this zone. In Sri Lanka, formerly Ceylon, the climate is tropical, and the weather is hot and humid throughout the year. ��:���.`��$���c�=7�Eî��.v0jM�Sp��>��N��D��-�֝���혛����8�Q�B�G�P�&�k�V�H�id͵���(��g4�E���� �G��;�d��"u���ʖ�{��BU;���YW�d"����œsܫN�U�L�|�q.�&C�/��T��ǵ+2��e>��u,x*�.|���A��A��5���!����QP��d� �7- (`ll&Al �(`� b �B fˀH2 Ł Land Area : 62705 Km .

Annual Weather Averages in Kandy Based on weather reports collected during 2005–2015. Climatic zones (dry, intermediate and wet zones) of Sri Lanka, arbitrarily demarcated based on the annual rainfall. These six sites were selected based on the availability of long-term crop production data and meteorological data. The emphasis is on daily rainfall rather than on longer-period totals, in particular the number of daily falls exceeding given threshold totals. Annual and four temporal seasons: Southwest monsoon (SWM), Northeast monsoon (NEM), First Inter-monsoon (FIM) and Second Inter-monsoon (SIM) were used for the analysis. Climatic Zones for Stability Studies Know different climatic zones by ICH in the world for stability conditions including Temperate, Mediterranean / subtropical, Hot dry, Hot humid / tropical and hot & higher humidity zones. 0000002605 00000 n Three zones can be divided by its distinguished elevation: the central highland, the plains, and the coastal belt. Each estate has an average tree density of 64 palms per acre. Most of the rivers are short and frequently interrupted by the discontinuities of terrain. All information on the ant subfamilies, genera and species (where possible) from the surveys was combined to report the distribution of each of them in the four climatic zones of Sri Lanka. In the northeast and the southwest, the coasts cut across the stratification of crystalline rocks, cliffs, bays, and offshore islands, creating one of the world's best natural harbors at Trincomalee on the northeastern coast and a smaller rock harbor at Galle on the southwestern coast. Colombo, Sri Lanka's largest city (6° 55′ N, 79° 51′ E) has a warm, humid climate (Köppen-Geiger classification = Af − Tropical Rainforest Climate), with no seasonal differences in temperature or moistness and year-round rainfall. The highest point is Pidurutalagala at 2,524.13 m (8,281.3 ft). Based on mean annual rainfall, Sri Lanka has three climatic zones: wet (>2500mm mean annual rainfall), intermediate(1750–2500mm mean annual rainfall) and dry zone (<1750mm mean annual rainfall) (Punyawar-dena et al., 2003). A coastal belt surrounds the island, consisting of scenic sandy beaches and lagoons. 0000001514 00000 n Climate Change Secretariat Sri Lanka The developed bioclimatic chart is aimed to be evaluated against different climatic conditions of the country. 0000000016 00000 n � Merged citations.

Sri Lanka is a tropical country with a year-round hot climate, moderated by oceanic winds. xref Sri Lanka is an island in the Indian Ocean, located to the south of Indian Subcontinent. Historical and predicted rainfall records and spatial interpolation of temporal trends were analyzed to identify its impact on major climatic zones of Sri Lanka. They have rain during the southwest monsoon and constitutes the lowland rain forests up to an elevation about 900 meters. Sri Lanka experiences a typical bi-modal rainfall. The average rainfall patterns during each monsoon seasons are showed in the figure 1. According to Köppen and Geiger, this climate is classified as Af.

Data from GHCN version 2.0 of monthly precipitation from 1930 - 2000 of 15 gauging stations in Sri Lanka were used in this study. The largest river is the Mahaweli Groundwaters in these three zones are extracted mainly for drinking and irrigation from metamorphic hard rock aquifers and saprolite developed on metamorphic rocks. Background Samples of 226 new improved and 21 indigenous rice (Oryza sativa L.) varieties were collected from the rice fields in three climatic zones of Sri Lanka and concentrations of 18 trace elements (Li, B, Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Cd, Ba, Pb and Bi) were measured giving particular emphasis on Se, Cd and As using ICP-MS.
