Tropical Storm Chantal during August 2001 was a storm that failed to intensify over the few days prior to making landfall on the Yucatan Peninsula. An observational study of Tropical Storm Chantal is presented using a diverse dataset including remote and in situ measurements from the NASA ER-2 and DC-8 and the NOAA WP-3D N42RF aircraft and satellite. The authors discuss the storm structure from...

Addiction to alcohol or nicotine involves altered functioning of the brain's motivational systems. Altered functioning of the hypothalamic-pituitary-adrenocortical (HPA) axis may hold clues to the nature of the motivational changes accompanying addiction and vulnerability to addiction. Alcohol and nicotine show at least three forms of interaction with HPA functioning. Acute intake of both subst...

Many impact studies require climate change information at a finer resolution than that provided by Global Climate Models (GCMs). In the last 10 years, downscaling techniques, both dynamical (i.e. Regional Climate Model) and statistical methods, have been developed to obtain fine resolution climate change scenarios. In this study, an automated statistical downscaling (ASD) regression-based appro...

The South China Sea summer monsoon (SCSSM) is crucial for the East Asian system, which has been detected from plenty of aspects, while its prediction relatively less investigated on subseasonal timescale. 1–31-day predictions SCSSM, including fundamental dynamic and thermodynamic characteristics, indices, onset date associated circulations, are examined diagnosed different climate systems, i.e....

The Madden–Julian oscillation (MJO) is known as the dominant mode of tropical intraseasonal variability and has an important role in the coupled-atmosphere system. This study uses numerical model experiments to investigate the influence of the MJO activity on weather predictability in the midlatitudes of the Northern Hemisphere. The National Aeronautics and Space Administration (NASA) Goddard L...

abstract drastic precipitations in unmorally times always are one of the important factors that created abundant damages in different geographical areas. in this research, three precipitations that occurred in summer 2009 in mashhad were investigated. the investigation of variation graphs of meteorological parameters show significant decreasing of air pressure and temperature and increasing of ...

Abstract. The co-polluted days by ozone (O3) and PM2.5 (particulate matter with an aerodynamic equivalent diameter of 2.5 µm or less) (O3–PM2.5PDs) were frequently observed in the Beijing–Tianjin–Hebei (BTH) region warm seasons (April–October) 2013–2020. We applied 3-D global chemical transport model (GEOS-Chem) to investigate physical characteristics O3–PM2.5PDs composited analyses such that c...

weather process prediction is the tool for managers to planning the future political for maximum operation. the aim of this research is relation investigation of large scale synoptically patterns with seasonal rainfall of khorasan province. in this research, we have analyzed 37 years of rainfall data in khorasan province that is located the northeastern part of iran .we attempted to train adapt...

This article explores the relationship between vertical wind shear (VWS) and tropical cyclone (TC) genesis in Mozambique Channel (MC) for period 1979–2019. Additionally, SST, low-level relative vorticity, 700 hPa humidity upper-level divergence were also analyzed peak cyclogenesis months to explore their contributions. The analyses done using NCEP/NCAR Reanalysis-1 atmospheric fields, monthly O...

The temperature data from 3 meteorological stations (Kashi, Ruoqiang, and Hotan) in the South of Tarim River Basin (STRB) during 1964-2011 were analyzed by Mann-Kendall test and correlation analysis. The results from Mann-Kendall test show that the surface temperature (ST), 850 hPa temperature (T850), and 700 hPa temperature (T700) exhibited upward trends, while 300 hPa temperature (T300) revea...
