Climatology and variability of wind speeds along the southwest coast of India derived from Climate Forecast System Reanalysis winds
Abdulla, C.P.; Aboobacker, V.M.; Shanas, P.R.; Vijith, V.; Sajeev, R.; Vethamony, P. (Wiley, 2022)Wind climate along the southwest coast of India (Kerala coast) has been analysed using 41 years of Climate Forecast System Reanalysis (CFSR) winds to delineate long-term trends and variability.The study reveals significant ... -
Evolution mechanism of contrasting phases of consecutive IOD events from 1994 to 1998
Anil, N.; RameshKumar, M.R.; Sajeev, R.; Saji, P.K. (CSIR-NISCAIR, 2021)The Dipole Mode Index (DMI), an Index used to represent the Indian Ocean Dipole (IOD), shows a back to back occurrence of positive and negative IOD events during the period 1994 to 1998. The year 1994 was a strong positive ... -
Role of distinct flavours of IOD events on Indian summer monsoon
Anil, N.; RameshKumar, M.R.; Sajeev, R.; Saji, P.K. (Springer, 2016)The summer monsoon contributes to about 75 % of mean annual rainfall over the various meteorological subdivisions of India. The role of ocean–atmosphere phenomena such as Indian Ocean Dipole (IOD) and El Nino-Southern ... -
Seasonal changes of the sediment size distribution and stability along the beaches of Kerala, south west coast of India
Sajeev, R.; Sankaranarayanan, V.N.; Chandramohan, P.; Nampoodiripad, K.S.N. (NISCAIR, CSIR, 1996)Mean grain size distribution under different environmental conditions along the coast of Kerala showed considerable spatial variation (0.14-0.96 mm). Standard deviation values indicated a very well sorted class along all ... -
Statistical analysis on extreme wave height
Teena, N.V.; SanilKumar, V.; Sudheesh, K.; Sajeev, R. (Springer, 2012)The classical extreme value theory based on generalized extreme value (GEV) distribution and generalized Pareto distribution (GPD) is applied to the wave height estimate based on wave hindcast data covering a period of 31 ... -
Studies on sediment transport along Kerala Coast, south west coast of India
Sajeev, R.; Chandramohan, P.; Josanto, V.; Sanakaranarayanan, V.N. (NISCAIR, CSIR, 1997)Longshore sediment transport characteristics of the Kerala Coast have been examined to delineate various physical processes affecting the different coastal environments. Monthly averages of the daily LEO (Littoral Environmental ... -
Wave refraction and prediction of breaker parameters along the Kerala Coast, India
Sajeev, R.; Chandramohan, P.; SanilKumar, V. (NISCAIR, CSIR, 1997)Numerical wave refraction study for the Kerala Coast has been carried out for waves representing southwest monsoon (June-September), northest monsoon (October-February) and fair weather period (February-May). Distribution ...
