Performance Evaluation of the MPAS Model in Simulating Southeast Asian Rainfall Characteristics

International Journal of Climatology, EarlyView.
This study evaluates the performance of the Model for Prediction Across Scales–Atmosphere (MPAS) in reproducing key rainfall characteristics over Southeast Asia (SEA) during 2000–2020, using the MSWEP dataset as reference. MPAS realistically captures the observed meridional rainfall gradient, with higher rainfall in the south and lower in the north, as

Indian Ocean Dipole intensifies Benguela Niño through Congo River discharge

Communications Earth & Environment
Benguela Niños are episodes of unusual El Niño-like warming in the upwelling zone off the coast of southwest Africa, with consequential impacts on marine ecosystems, coastal fisheries and regional weather. The strongest Benguela Niño in the past 40 years

Desertification Risk: Bibliometric Analysis and Future Research Directions

Land Degradation &Development, EarlyView.
ABSTRACT Desertification, driven by climatic and anthropogenic factors, is one of the most pressing global environmental challenges, causing significant economic, ecological, and social consequences. A bibliometric analysis was performed to identify research trends and gaps in the desertification risk topic.

How Predictable is the Indian Ocean Dipole?

Monthly Weather Review, 2012
Abstract In light of the growing recognition of the role of surface temperature variations in the Indian Ocean for driving global climate variability, the predictive skill of the sea surface temperature (SST) anomalies associated with the Indian Ocean dipole (IOD) is assessed using ensemble seasonal forecasts from a selection of ...

The role of soil moisture in the inland penetration of Indian monsoon low‐pressure systems

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We use the Advanced Weather Research and Forecasting model to examine the role of soil moisture in the inland penetration of Indian monsoon low‐pressure systems (LPSs). We find that LPSs penetrate deeply into India despite a dry land surface; however, their inland penetration is adversely affected when there is a reduction in the total surface heat ...

Using a causal effect network approach to quantify the impact of ENSO teleconnections on summer monsoon precipitation over the Himalayas and key regional circulations

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We quantified the causal effect (CE) of linkages between four monthly climate indices ENSO, SMHP, RWC, and MHC for 1940–2022 with a time lag of one month. The results show CE values from (1) ENSO to SMHP of −0.33$$ -0.33 $$ to −0.44$$ -0.44 $$ (i.e., a one standard deviation (SD) increase in ENSO causes a decrease in SMHP of −0.33$$ -0.33 $$ to −0.44$$

A biological dipole variability in the Indian Ocean

Environmental Research Letters, 2023
Abstract The Indian Ocean Dipole (IOD) is a prominent mode of climate variability in the tropical Indian Ocean (IO). It exerts a significant influence on biological activities in this region. To elucidate the biological response to the IOD, previous research has introduced the biological dipole mode index (BDMI). However, the delineation

Does vertical wind shear increase tropical cyclone rain?

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A 26‐year modern precipitation dataset is used to systematically assess tropical cyclone (TC) rainfall responses to vertical wind shear (VWS). VWS enhances rainfall volume in TCs by up to 23%, despite reducing storm intensity, revealing a trade‐off where VWS mitigates wind damage but potentially amplifies flood risk.

Environmental Factors Controlling the Precipitation in California

Atmosphere, 2021
Using observational data covering 1948–2020, the environmental factors controlling the winter precipitation in California were investigated. Empirical orthogonal function (EOF) analysis was applied to identify the dominant climate regimes contributing to

Indian Ocean Dipole influence on South American rainfall [PDF]

Geophysical Research Letters, 2008
The rainfall anomalies over South America are found to be influenced by the Indian Ocean Dipole (IOD). Between subtropical La Plata Basin and central Brazil, the IOD excites a dipolar pattern in rainfall anomalies; rainfall is reduced (enhanced) over latter (former) during austral‐spring, when IOD reaches its peak phase.
