Introduction
I like working with numerical models and topics related to Atmospheric Physics. I enjoy using programming tools to analyze big data and finding patterns. My research interest includes and not limited to large-scale atmospheric circulation, Seasonal-to-decadal variations in large-scale atmospheric properties, and climate response to forcing from anthropogenic and natural sources.

Article
Full-text available
In early 2018 Cape Town’s water supply dropped so severely that the city ran the risk of running out of water, precipitating what is now known as the “Day Zero” crisis. Reservoir storage simulations point towards anomalously low rainfall as the driver of the water crisis, but evaluation of the observational record is still needed. Here, Natalie Bur...

The anticyclonic high-pressure systems over the southern-hemisphere, subtropical oceans have a significant influence on regional climate. Previous studies of how these subtropical anticyclones will change under global warming have focused on austral summer while the winter season has remained largely uninvestigated, together with the extent to whic...

Subtropical anticyclones and midlatitude storm tracks are key components of the large-scale atmospheric circulation. Focusing on the southern hemisphere, the seasonality of the three dominant subtropical anticyclones, situated over the South Pacific, South Atlantic, and South Indian Ocean basins, has a large influence on local weather and climate w...

Tropical cyclones (TCs) in the Bay of Bengal (BoB) are among the most devastating events in nature, significantly influencing human life. They affect the region between April and December, being separated into two distinct phases: the pre-monsoon (April-May-June, AMJ) and post-monsoon (October-November-December, OND), with little activity during th...

Bangladesh and northeast India are the most densely populated regions in the world where severe flood-causing extreme rainfall events kill hundreds of people and cause socioeconomic losses regularly. Due to local high-topography, the moisture-carrying monsoon winds converge near southeast Bangladesh (SEB) and northeast Bangladesh and India (NEBI),...

To predict the future state of the earth system on multiyear timescales, it is crucial to understand the response to the changing external radiative forcing (CO2 and Ozone). In this study, we use a 1-degree GEOS-MITgcm coupled general circulation model to understand the response to different levels of observed external forcing from past decades. Re...

Earth's hydrological cycle is expected to intensify in response to global warming, with a “wet‐gets‐wetter, dry‐gets‐drier” response anticipated over the ocean. Subtropical regions (∼15°–30°N/S) are predicted to become drier, yet proxy evidence from past warm climates suggests these regions may be characterized by wetter conditions. Here we use an...

Southern hemisphere subtropical anticyclones are projected to change in a warmer climate during both austral summer and winter. A recent study of CMIP 5 & 6 projections found a combination of local diabatic heating changes and static-stabilityinduced changes in baroclinic eddy growth as the dominant drivers. Yet the underlying mechanisms forcing th...

We present results from a new, global, high-resolution (∼3-km for ocean and ∼6-km for atmosphere) realistic earth system simulation. This simulation allows us to examine aspects of small-scale air-sea interaction beyond what previous studies have reported. Our study focuses on recurring intermittent wind events in the Gulf Stream region. These even...

Bangladesh receives most of its precipitation from June to September in the form of rainfall as a part of the Asian summer monsoon system. Bangladesh is a relatively flat region, surrounded by the southern Himalayas and Meghalaya Plateau in the north, Arakan Mountains in the east, and the Bay of Bengal (BOB) in the south. Although several studies h...

An ‘emergent constraint’ (EC) is a statistical relationship, across a model ensemble, between a measurable aspect of the present day climate (the predictor) and an aspect of future projected climate change (the predictand). If such a relationship is robust and understood, it may provide constrained projections for the real world. Here, Coupled Mode...

Subtropical Anticyclones located over the subtropical oceans of both hemispheres are a crucial element of large-scale atmospheric circulation. Subtropical Anticyclones dominate midlatitude weather and climate by influencing moisture transport, cyclone tracks, sea surface temperature, and precipitation. However, the underlying mechanisms driving the...

Conference Paper
Several studies have investigated how the atmospheric circulation associated with the Southern Hemisphere (SH) Subtropical Anticyclones (SA) will change in climate model projections. The winter season has however remained largely uninvestigated, as well as the extent to which the mechanisms proposed in the literature explain the inter-model spread...
Conference Paper
The Coupled Model Intercomparison Project (CMIP), a worldwide multi-model framework for climate experiments and projections, recently began releasing output from the CMIP6 coordinated effort to the scientific community for analysis. The climate models used to undertake CMIP6 represent the state-of-the-art, with the latest scientific understanding i...

Ensemble re-forecast experiments are performed for the boreal winters of 2015/16 (an El-Nino year) and 2016/17 in order to understand the origin of the ˜ highly unexpected low precipitation over Southern California (SoCal) during 2015/16. The specific hypothesis tested is that the December-March anomalies in: (a) SoCal precipitation (highly negativ...

High-pressure systems over the subtropical oceans have a significant influence on local climate. The South Atlantic Subtropical High (SASH), upon which this study is focused, influences South Atlantic wind stress and sea surface temperatures, as well as precipitation over southern Africa and southeastern South America. Several studies have investig...

Question
I wanted to couple WRF V3.4.1 and ROMS (Regional Ocean Modeling System) to study some properties of air-sea interaction. Where can i find valuable information about setting and other setup information in web?
I have a very low configured computer resource (A small server with 12 gb ram). Is it possible to run the models in there for 5 days data?
Thanks in advance
Question
Is it possible to get images of any particular tropical cyclones eye from any Satellite (as like Landsat) continuously (6 or 4 hrs period) for 3 or 4 days?
