Arctic sea-ice decline causes intense summer monsoon precipitation events over South Asia under greenhouse warming
Arctic sea-ice decline has been accelerating under greenhouse warming. In this study, we investigate the tropical precipitation response to declining Arctic sea-ice using observations and climate model simulations. Observational evidence and idealized model experiments in which the Arctic becomes seasonally ice free under greenhouse warming reveal association between the Arctic sea-ice decline and intense precipitation events (IPEs) over South As…
Improved storm surge prediction and extreme sea level future projections in the Indian Ocean using deep learning
Accurate storm surge and extreme sea level (ESL) prediction is crucial for effective coastal flood monitoring and hazard management. However, dynamical models for the Indian Ocean often exhibit significant biases compared to historic tide gauge (TG) based sea level records, highlighting the need for improved methods. To address this gap, we applied a long short-term memory (LSTM) deep learning network to reconstruct hourly storm surges across 29 …
Future intensification of Northern Hemisphere monsoons due to declining remote aerosol pollution
Anthropogenic aerosol emissions have significantly shaped historical monsoon precipitation, yet uncertainties persist in the projected response to future emissions. This study employs models contributing at least ten ensemble members to the Detection and Attribution Model Intercomparison Project—MIROC6 and CanESM5—to examine the mid-century response of the Northern Hemisphere (NH) summer monsoons to changes in aerosol burdens. We focus on a scena…
Self-esteem as a mediator of the relationship between imposter phenomenon and academic performance among college students
This exploratory study examined the mediating role of self-esteem in the relationship between the imposter phenomenon and academic performance among college students and further investigated age as a moderator. A sample of 150 students (66 males, 84 females; mean age = 24.11) completed assessments using the Clance Impostor Phenomenon Scale, Rosenberg Self-Esteem Scale, and Academic Performance Scale. Correlation analysis indicated a significant i…
Understanding the soil water dynamics during excess and deficit rainfall conditions over the core monsoon zone of India
Observations of soil moisture (SM) during excess and deficit monsoon seasons between 2000 to 2021 present a unique opportunity to understand the soil water dynamics (SWD) over core monsoon zone (CMZ) of India. This study aims to analyse SWD by investigating the SM variability, SM memory (SMM), and the coupling between surface and subsurface SM levels. Particularly intriguing are instances of concurrent monsoonal extremes, which give rise to compl…
Extreme sea level rise along the Indian Ocean coastline
Anthropogenic sea-level rise poses challenges to coastal areas globally. The combined influence of rising mean sea level (MSL) and storm surges exacerbate the extreme sea level (ESL). Increasing ESL poses a major challenge for climate change adaptation of nearly 2.6 billion inhabitants in the Indian Ocean region. Yet, knowledge about past occurrences of ESL and its progression is limited. Combining multiple tide-gauge and satellite-derived sea-le…
Abrupt climate change at ~2800 yr BP evidenced by a stalagmite record from peninsular India
This study presents an analysis of the Indian summer monsoon (ISM) rainfall variations for a 1460-year period (1720–3180, Before Present BP: 1950 AD), based on a long record of stable isotopic variations (δ 18 O) with high temporal resolution (~annual) obtained from a U-Th dated stalagmite from the Kadapa cave in peninsular India. This stalagmite proxy record captures variations associated with wet and dry monsoons on decadal to centennial time-s…
Prolonged monsoon droughts and links to Indo-Pacific warm pool
Intensified monsoon and spatiotemporal changes in precipitation patterns in the NW Himalaya during the early-mid Holocene
Projected Climate Change in the Hindu Kush–Himalayan Region By Using the High-resolution Regional Climate Model PRECIS
The Hindu Kush–Himalayan (HKH) region is characterized by a variety of climatic conditions from tropical to alpine. It has been documented that the rates of warming in the HKH region are significantly higher than the global average and that the warming is occurring at much higher rates in the high-altitude regions than in the low-altitude regions. Mountainous environments are considered sensitive indicators of climate change. Hence this study exa…
