Transport of Particulate Matter Due to Meteorological Changes Analyzed by HYSPLIT

open access: yesRevista de Chimie, 2022
The air quality in the urban region varies based on the sources of air pollution from regions near and far. Any pollution produced in the urban region affects the locality near the pollution source and also adjacent distant regions. The study of the interaction between the local weather patterns of a region and the pollutants in the air is needed for ...

Simulation of cucumber downy mildew Spread and sedimentation based on HYSPLIT

open access: yesJOURNAL OF ADVANCES IN AGRICULTURE, 2023
Cucumber downy mildew is a typical fungal airborne disease in which pathogenic spores are transmitted remotely by air currents, resulting in regional endemics. It is of great significance to study and analyze the temporal and spatial changes of downy mildew spores, especially the trajectory and sedimentation concentration of spores propagating with ...

The effects of moisture sources and local parameters on the 18O and 2H contents of precipitation in the west of Iran and the east of Iraq

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2020
Iran and Iraq face a water shortage crisis especially in the recent decade. Hence, the regions with high potential water resources are highly important to these countries. Precipitation sampling for 18O and 2H analyses was conducted in 10 stations in the

Forecasting volcanic ash deposition using HYSPLIT

open access: yesJournal of Applied Volcanology, 2017
A major source of error in forecasting where airborne volcanic ash will travel and land is the wind pattern above and around the volcano. GNS Science, in conjunction with MetService, is seeking to move its routine ash forecasts from using the ASHFALL program, which cannot allow for horizontal variations in the wind pattern, to HYSPLIT, which uses a ...

Analysis on PM2.5 transport trajectories and potential pollution source for Wenzhou area(温州市PM 2.5输送轨迹特征和潜在污染源区分析)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2015
利用HYSPLIT模式和全球再分析资料模拟2012~2014年温州市大气输送的后向轨迹.结合聚类分析方法、潜在源贡献因子分析法、浓度权重轨迹分析法得到分季节的温州大气输送轨迹、污染潜在源区以及潜在源区污染浓度.温州地区春、秋、冬季节容易受西北、偏北、西南等内陆气流影响,来自偏北、西南方向的短轨迹由于移动缓慢、扩散能力差,PM 2.5的浓度值高;夏季主要受较为清洁的海洋性气流影响,PM 2.5的浓度值低.影响温州的潜在污染源区主要集中在3块区域:西北及中原地区、华北地区和江西-福建-浙江周边区域.其中西北、

Dispersion simulations using HYSPLIT for the Sagebrush Tracer Experiment

open access: yesAtmospheric Environment, 2018
Abstract The Sagebrush experiment, led by NOAA's Field Research Division of the Air Resources Laboratory, consisted of five releases (intensive observation periods, or IOPs) of a chemically inert trace gas on five days in October 2013. All releases occurred in the afternoon under either near neutral stability conditions with high wind speeds or ...
