Tropical Cyclone Rainfall Spatial Asymmetries in the Lesser Antilles

International Journal of Climatology, EarlyView.
Rainfall is not proportional to the Saffir‐Simpson wind‐based categories. Lower category tropical cyclones (TS, H1, H2 and H3) can generate more intense rainfall than H4 and H5. Rainfall is asymmetric; as a tropical cyclone intensifies or weakens, the location of peak rainfall shifts.

Dynamics and model representation of two contrasting extreme precipitation events in the Sahel

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Hovmöller diagrams of the two investigated extreme precipitation events in Mali are shown for (i) IMERG observations, and ICOsahedral Nonhydrostatic model (ICON) runs with parameterization of explicit convection (ii) enabled and (iii) disabled. This work highlights that the commonly perceived benefit of using explicit convection in a state‐of‐the‐art ...

Artificial Intelligence-Based Precipitation Estimation Method Using Fengyun-4B Satellite Data

Remote Sensing
This paper proposes a novel precipitation estimation method based on FY-4B meteorological satellite data (FY-4B_AI). This method facilitates the spatiotemporal matching of 125 features derived from the multi-temporal and multi-channel data of the FY-4B ...

Evaluation of GPM-Era Satellite Precipitation Products on the Southern Slopes of the Central Himalayas Against Rain Gauge Data

Remote Sensing, 2020
The Global Precipitation Measurement (GPM) mission provides high-resolution precipitation estimates globally. However, their accuracy needs to be accessed for algorithm enhancement and hydro-meteorological applications.

A New Perspective for Charactering the Spatio‐temporal Patterns of the Error in GPM IMERG Over Mainland China

Earth and Space Science, 2021
Evaluation is necessary and informative for processing and applying the precipitation products. However, researchers mainly focus on the statistical indicators of satellite‐based precipitation evaluation over manually determined regions without further ...

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 ...

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.

Assessment of Satellite-Based Precipitation Products for Estimating and Mapping Rainfall Erosivity in a Subtropical Basin, China

Remote Sensing, 2022
Rainfall erosivity is an important indicator for quantitatively representing the erosive power of rainfall. This study expanded three satellite-based precipitation products (SPPs) for estimating and mapping rainfall erosivity in a subtropical basin in ...

The characteristics of squall lines in the Southeast Asia region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Squall lines over the Maritime Continent were analysed using 20 years of IMERG GPM data and classified into four regional clusters. Significant regional differences were found in their size, intensity, lifespan, and propagation. Nighttime squall lines are primarily driven by the convergence of opposing offshore flows and the convergence of monsoonal ...

Spatial downscaling analysis of GPM IMERG precipitation dataset based on multiscale geographically weighted regression model: a case study of the Inner Mongolia Reach of the Yellow River basin

Frontiers in Environmental Science
The Inner Mongolia Reach of the Yellow River Basin is characterized by a relative scarcity of meteorological stations. While satellite precipitation products can complement observations from meteorological stations, their limited spatial resolution ...
