In the present paper an attempt has been made to estimate the recent SST ( sea surface temperature ) trends in the coastal zones of the northern Indian Ocean. For this purpose the satellite derived grid point SST data for the period 1985-1998 has been utilized. The SST has shown consistent increasing trends in all the seasons in the coastal belts of Pakistan and the northwestern India upto Bombay (Mumbai). In the coastal regions of the islands the increasing trend is confined to the summer only. During the winter season the SSTs in the island regions have registered decreasing trends. This is indicative of an extension of the continental influence towards the island regions. It has been found that the interannual mode of SST variation dominates the linear SST trends which is characterised by the Quasi Biennial Oscillations (QBO) and the El Nino/ Southern Oscillation (ENSO) scale cycle. QBO ha...

In this study, Weather Research and Forecasting (WRF-ARW) model with two nested outer and inner domains at spatial resolutions of 9 and 3 km respectively has been used to retrieve rain that occurred at Bhur (latitude 26.54 Longitude 90.26, Elevation 375 m) in the southern part of Bhutan on 18 July 2010. The spell of very heavy rainfall of about 430 mm was recorded in 24 hours of 18 July 2010 over the study area. The rainfall amount over Bhur has been underestimated by both the cumulus parameterization schemes. The results show that the KainFritsch (KF) scheme was able to capture the heavy rainfall event better than the Grell-Devenyi (GD) ensemble scheme over the study area. The output of the model in each resolution ...

Many low lying coastal regions of South Asia are adjacent to river deltas and have large population. The dense population, poor economy and several other socioeconomic factors make these areas most vulnerable to the impact of climate change. Variability of sea surface temperature (SST) is important as the duration and intensity of SST provide the basis for studies related to climatic change scenario. In this study an attempt has been made to estimate the recent SST trends in the coastal waters of some cities, which lie on the Arabian Sea and Bay of Bengal. The annual and interannual variability has also been studied. The SST variations have then been linked with the El Nino and La Nina events. The NOAA-NASA Pathfinder Advanced Very High Resolution Radiometer (AVHRR) SST fields from 1985-1998, created in the Jet Propulsion Laboratory (JPL), USA are used in this study. Here the quality of data is an important factor to obtain reliable estimates of Sea Surface Temperature (SST) trends and other related parameters. However, this is not possible with the conventional type data, due to low quality as well as sparse data in the region. Though the satellite based SST climatologies have shorter observation lengths, they can provide reliable estimates of recent SST variability over a large oceanic areas with sparse or no data. Increasing trend of SST is observed throughout all the seasons in the northern Arabian Sea extending from Oman to Karachi and Mumbai and further south to Salalah and Colombo. However, in coastal islands stations further south of India such as at Colombo the increment is not significant. Though the increasing trend in SST during winter is not significant, nevertheless it shows the increasing influence of cold spells on this Island. An interesting situation has been observed in the Bay of Bengal. On an average, increasing trends in the annual SST were observed in Visakhaputnam. But at the stations located in the northeastern part of Bay of Bengal, namely Hiron Point and Cox's Bazar reverse conditions are observed. In the Southern Bay of Bengal variations in SST is not significant which reflects in the SST analysis of Chennai and Port Blair stations. Location of these stations at lower latitudes (near by equator) probably is the reason for this insignificant change. It has been found that the interannual mode of SST variations dominate the linear SST trends which is characterized by the El Nino Southern Oscillations (ENSO) scale cycle.
