Performance evaluation of regional weather predictions with the Model for Prediction Across Scales – Atmosphere (MPAS‐A) over the Maritime Continent

Quarterly Journal of the Royal Meteorological Society, EarlyView.
As part of the ongoing efforts to develop next‐generation forecasting systems at the Meteorological Service Singapore, this study presents the setup and evaluation of the SINGV_NG(MPAS) system. Overall, the SINGV_NG(MPAS) system outperforms European Centre for Medium‐Range Weather Forecasts (ECMWF) deterministic forecasts in capturing heavy rainfall ...

Simulation of regional rainfall observation using urban surveillance camera networks

Environmental Research Letters
Widespread surveillance cameras show excellent potential for high spatial and temporal resolution rainfall observation. As the accuracy of surveillance camera-based rain gauges (SRGs) continues to improve, surveillance camera-based rainfall observation ...

Moisture and wind effects of Rossby waves on Western Pacific Intertropical Convergence Zone breakdown events

Quarterly Journal of the Royal Meteorological Society, EarlyView.
(a) Organized convection: clouds are clustered at the southern edge of the domain, aligning with the warmest SST. Northeasterly winds prevail, facilitating convection confinement to the southern part of the domain. (b) ITCZ breakdown: the clouds are spread throughout the domain.

Modelling the impact of high rise buildings in urban areas on precipitation initiation [PDF]

, 2007
The impact of urban areas upon precipitation distribution has been studied for many years. However, the relative importance of the distribution and type of surface morphology and urban heating remains unclear. A simple model of the surface sensible heat

Utilization of high resolution short range weather forecast for agro advisory services

Journal of Agrometeorology, 2010
Agriculture is heavily weather dependent in India. The economy of the country is largely synchronized to the success of agriculture every year, as it contributes nearly 25% to gross domestic product (GDP). Farming community, planners and line department

Assessing high‐resolution numerical models and bottom‐boundary factors for a Mediterranean heavy precipitation event

Quarterly Journal of the Royal Meteorological Society, EarlyView.
State‐of‐the‐art, convection‐permitting NWP models reproduced the main features of the October 22–23, 2019 heavy precipitation event in Catalonia. However, slight configuration changes yielded varying streamflow responses and statistical performance, highlighting the challenge of simulating these events in Mediterranean medium‐sized basins ...

WRF-Model Data Assimilation Studies of Landfalling Atmospheric Rivers and Orographic Precipitation Over Northern California [PDF]

, 2014
In this study, data assimilation methods of 3-D variational analysis (3DVAR), observation nudging, and analysis (grid) nudging were evaluated in the Weather Research and Forecasting (WRF) model for a high-impact, multi-episode landfalling atmospheric ...

From Predicting Solar Activity to Forecasting Space Weather: Practical Examples of Research-to-Operations and Operations-to-Research

, 2013
The successful transition of research to operations (R2O) and operations to research (O2R) requires, above all, interaction between the two communities.

An anatomy of fog over Nova Scotia under a ridge on 8 September 2021

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Image from an aircraft traveling eastward at 1230 UTC (0930 Atlantic Daylight Time, ADT) on 8 September 2021. The view is to the southeast over the eastern coast of Nova Scotia. The leading head of the fog bank is in the image with its base on the sea surface.

Utilization of satellite data in mesoscale modeling of severe weather [PDF]

The Visible Infrared Spin Scan Radiometer Atmospheric Sounder (VAS) data were used to model the 36 hour cyclogenesis period over the Pacific Ocean. Various combinations of VAS data, conventional radiosonde data, and gridded data from the National Weather
