Long-term and continuous measurements of aerosol concentration optical properties from the Challakere Climate Observatory, located in a remote rural semi-arid region northwest Bengaluru, are examined for impact prolonged phased national lockdown during COVID-19 pandemic The analyses revealed that lockdown, which almost brought all anthropogenic activities (particularly associated with fossil fu...

1. introduction dust storm is an important atmospheric phenomenon. it has important environment, health, economic and social activities due to penetration of suspended particles of dust to the atmosphere. measurements resulting from earth and satellite stations show the fact that particles of dust in storms, remain in the nature for a long time. they can get far away by wind, hundreds of kilome...

Abstract Detailed precipitation characteristics coupled with equatorial Rossby and Kelvin waves are investigated. We prepare a rainfall event dataset using the Tropical Rainfall Measurement Mission (TRMM) Precipitation Radar (PR) level 2 data. Utilizing three indices, area size, maximum echo-top height, stratiform ratio, events classified into mesoscale convective system (MCS), deep, congestus,...

We describe the large-scale meteorological conditions that affected atmospheric chemistry over Mexico during March 2006 when several field campaigns were conducted in the region. In-situ and remote-sensing instrumentation was deployed to obtain measurements of wind, temperature, and humidity profiles in the boundary layer and free atmosphere at four primary sampling sites in central Mexico. Sev...

Forest fires are one of the natural disasters that concern all countries in globalizing world terms their effects and consequences. Fires a vital threat causes burning millions hectares forest areas worldwide every year, causing loss life property. An early warning system helps people respond to dangers promptly appropriately. In scope this study, Antalya-Manavgat (starting on 28 July 2021 endi...

This paper is a try to become familiar with strategic program, strategic management and studying various theoretic aspects and its performance. On the other hand, by studying Iran’s meteorology organization as a pioneering one, we investigated third and fourth advancement program of this organization, then the efficacy of common indexes in compiling strategic program of organization will be com...

29 The influence of synoptic-scale circulations on air quality is an area of increasing interest to 30 air quality management in regards to future climate change. This study presents an analysis 31 where the dominant synoptic " types " over the region of Melbourne, Australia are determined 32 and linked to regional air quality. First, a self-organising map (SOM) is used to generate a 33 time se...
