Analysis of water vapor during short-time heavy rainfall events at the edge of subtropical high in Liaoning Province

暴雨灾害
The short-time severe rainfall at the edge of the western Pacific subtropical high (referred to as the Subtropical High) is characterized by strong bursts, concentrated precipitation, and low predictability, often posing challenges for forecasting. Eight

Identifying Dust Emission in South Khorasan, South-Western Asia. [PDF]

Desert
Atmospheric dust has a significant impact on air quality and human health. Based on visibility, dust events are defined as dusty days and dust storms. South Khorasan, which lies between the Karakum Desert and the Sistan Plain, is affected by dust, and ...

NOAA’s HYSPLIT Atmospheric Transport and Dispersion Modeling System

Bulletin of the American Meteorological Society, 2015
Abstract The Hybrid Single-Particle Lagrangian Integrated Trajectory model (HYSPLIT), developed by NOAA’s Air Resources Laboratory, is one of the most widely used models for atmospheric trajectory and dispersion calculations. We present the model’s historical evolution over the last 30 years from simple hand-drawn back trajectories to

Errors in top-down estimates of emissions using a known source [PDF]

Atmospheric Chemistry and Physics, 2020
Air pollutant emissions estimates by top-down methods are subject to a variety of errors and uncertainties. This work uses a known source, a coal-fired power plant, to explore those errors.

Análise do comportamento das trovoadas no estado de alagoas, previsão à curto prazo Analysis of the behavior of thunderstorms in alagoas state, short-term forecasting

Revista Brasileira de Meteorologia, 2011
A frequência de trovoadas a partir de dados de satélite TRMM e do DECEA foi estudada para o período de 10 anos (de 1998 até 2007), onde se observou que as trovoadas foram mais frequentes nos meses de verão, com maior ocorrência no mês de março.

WRF-HYSPLIT model results.

, 2017
Surface concentration of 131I at 0 UTC, 5 November 2011 modeled with the HYSPLIT model [10] using the WRF meteorological data. The locations of Prague and Budapest are marked. Northward transport was caused by higher level winds.
