This paper investigates the role that air–sea interaction processes may play in interannual variability of south-eastern African summer rainfall. The principal spatial modes of south-eastern African summer rainfall are first identified using principal component analysis. Four modes are retained. The most important mode of variability is found to represent rainfall variability over most of the d...

At present no war is being fought in SEE. However this outward tranquility was imposedfrom outside through energetic military interventions by the West, the establishment of international military and security protectorates over parts of the region, as well as by stationing peace-keeping troops, international police, armed and unarmed foreign observers at the hottest trouble spots in SEE. The s...

Observed upper ocean currents south of Sri Lanka exhibit large, irregular fluctuations with periods of days to weeks. An ocean model driven by daily surface winds is able to reproduce the observed fluctuations. We find from model experiments that low frequency (30-50 day) intraseasonal variability (ISV) arises when Rossby waves radiated from the eastern boundary are amplified by hydrodynamic in...

New Mydidae species are described from the Afrotropical and Oriental regions including the first records of this family from several countries in eastern Africa (Kenya, Tanzania, and Uganda) and Mauritania in western Africa as well as Nepal and Thailand in Asia. The new species are, Leptomydinae: Leptomydas notossp. n. (south-western India), Leptomydas raptisp. n. (south-central Nepal), Leptomy...

Scrub typhus has been previously reported from north and eastern Indian states and areas such as Kashmir, Himachal Pradesh, Assam, Sikkim, and Darjeeling district of West Bengal. It has also been known to be endemic in some parts of South India (Eastern and Western Ghats). However, no cases have ever been reported from the southern districts of West Bengal. Here, we report five cases of scrub t...

This boundary Mountains with Kulon Progo Tertiary volcanic In field, these lineament zones create Bogowonto river two different geological styles. influence this on dynamic and important to explained. study was condu...

coastal zone of sri lanka is a key to sustainable development of the country. the erosion of country’s coastal zone has been identified as a long standing problem. therefore, coastal sediment dynamics around the country has to be identified to develop an appropriate coastal zone management plan. remote sensing and gis techniques can be used for quantitative and qualitative analyses of coastal p...

occurs in regions with ambient temperatures of less than 30C and at least 25mm rainfall monthly for 6 months of the year (Gemmell, 1959). Echinococcus granulosus occurs most commonly along the eastern side of the continent in eastern Victoria, New South Wales and Queensland, in areas associated with the Great Dividing Range, and in the south-western corner of Western Australia (Jenkins and Macp...
