A study has been conducted on Extreme Weather Events (EWEs) induced mortalities in Jammu and Kashmir, India during 2010-2022. In the present study, we used the frequency of heavy rain, heavy snow, lightning/thunderstorm, Hailstorm and squall during the period 2010 to 2022 of 10 stations of J&K from India Meteorological Department. The mortalities o...

There have been major advances in the last few decades in our understanding of heavy rainfall during monsoon season due to substantial progress in both observation and numerical modelling of monsoon. All these resulted in more accurate forecast of heavy rainfall in short to medium range, (upto five days) with 40% improvement in accuracy of heavy ra...

A study has been conducted on frequency of western disturbances (WDs) and variability of precipitation over J&K during the period 1980 to 2019. The frequency of WD's from November to April during study period was determined and results showed that total 600 WD's cases were observed. The WD frequencies showed significant decreasing trend (p<0.01) du...

A study has been conducted on frequency of western disturbances (WDs) and variability of precipitation over J&K for the period 1980 to 2019. The frequency of WD’s from November to April during study period was determined and results showed that total 600 WD’s cases were observed during the period 1980-2019. It has been observed that on an average d...

Glacier mass balance time-series measurements have immense importance in comprehending the overall regional hydrology and meteorology of the mountain systems. Such assessments are critical in the Indus River basin (compared to the Ganga and Brahmaputra), which besides having a significant contribution from the glaciers, also exhibits considerable h...

While destruction associated with floods during the monsoon season and cyclones receives wide attention, the extreme weather in the form of hail, lightning and high winds have also caused widespread devastation over India on a small spatial scale in recent years, especially during the period of March to June. India Meteorological Department (IMD) o...

Kashmir Valley has been witnessing erratic snowfall events in recent autumns which severely impacted apple orchards and harvests. Here, we combine remotely sensed data and field observations to map snowfall distribution and snow depths during the recent snowfall events in November 2018 and November 2019. Besides, we used ERA-5 reanalysis climate da...

Although the subject area of climate change is vast, the changing pattern of rainfall is a topic within this field that deserves urgent and systematic attention, since it affects both the availability of freshwater and food production (Dore, 2005). Climate change is one of the key global challenges in the present era. It refers to a statistically s...

We present the first-ever mass-balance (MB) observation (2014–19), reconstruction (between 1978 and 2019) and sensitivity of debris-free Stok glacier (33.98°N, 77.45°E), Ladakh Region, India. In-situ MB was negative throughout the study period except in 2018/19 when the glacier witnessed a balanced condition. For MB modelling, three periods were co...

Western Himalaya receives heavy precipitation due to western disturbances embedded in the eastward moving upper tropospheric Rossby wave train, especially in the winter months. The interaction of intricate topography and large-scale atmospheric dynamics plays an essential role in determining the amount of precipitation over this region. The cold ai...

A diagnostic study has been carried out to analyse and understand the causes of unusual rainfall activity over Jammu & Kashmir (J&K) State during 2nd to 5th September, 2014. The careful examination of available historical rainfall data of India Meteorological Department (IMD) network reveals that many stations in the region received ever-highest 24...
