A cold air outbreak (CAO) is an extreme weather phenomenon that has significant social and economic impacts over a large region of the midlatitudes. However, dynamical mechanism occurrence evolution CAO events, particularly role stratosphere, not well understood. Through analysis one episode occurred on 27–31 January 2019 across much US Midwest, this study examined its thermodynamic structure i...

The substantial reliance of South Asia (SA) to rain-based agriculture makes the region susceptible food scarcity due droughts. Previously, most research on SA has emphasized meteorological aspects with little consideration agrarian drought impressions. insufficient amount in situ precipitation data across also hindered thorough investigation sector. In recent times, models, satellite remote sen...

Abstract. A new atmospheric ozone profile climatology has been constructed by combining daytime profiles from the Aura Microwave Limb Sounder (MLS) and Modern-Era Retrospective Analysis for Research Applications version 2 (MERRA-2) Global Modeling Initiative (GMI) model simulation (M2GMI). The MLS M2GMI are merged between 13 17 km (?159 88 hPa), with used stratospheric GMI primarily tropospheri...

Rapid industrialization and urbanization along with a growing population are contributing significantly to air pollution in China. Evaluation of long-term aerosol optical depth (AOD) data from models reanalysis, can greatly promote understanding spatiotemporal variations To do this, AOD (550 nm) values 2000 2014 were obtained the Coupled Model Inter-comparison Project (CIMP6), second version Mo...

Abstract. Dry conditions associated with the El Niño–Southern Oscillation (ENSO) and a positive Indian Ocean Dipole (IOD) are known to have caused major fire pollution events intense carbon emissions over vast spatial expanse of Indonesia in October 2006 2015. During these two events, substantial increase monoxide (CO) mixing ratio was detected by situ measurements at Lulin Atmospheric Backgrou...

MapReduce is an approach to high-performance analytics that may be useful to data intensive problems in climate research. It offers an analysis paradigm that uses clusters of computers and combines distributed storage of large data sets with parallel computation. We are particularly interested in the potential of MapReduce to speed up basic operations common to a wide range of analyses. In orde...

The wet deposition flux of black carbon (BC) over the Sichuan Basin is studied on basis MERRA-2 data from 1981 to 2020, aiming at investigating high BC in China terms long-term spatial-temporal trends and influences column mass density precipitation. In China, largest with a regionally-averaged value 1.00 × 10−2 μg m−2 s−1 observed, especially western southern regions values as 2.20 s−1. season...
