Fractionation of stable isotopes in precipitation runs through the water cycle, and deuterium excess is a second-order parameter linking water-stable oxygen hydrogen isotopes. It strongly influenced by under-cloud evaporation unsaturated air, especially arid climates. Based on improved Stewart model, this study used 670 isotope data measured meteorological element from 11 sampling points Januar...

In this study, wind forecasts derived from the European Centre for Medium-Range Weather Forecasts (ECMWF), National Centers Environmental Prediction (NCEP), Japan Meteorological Agency (JMA) and United Kingdom Office (UKMO) are evaluated lead times of 1–7 days at 10 m multiple isobaric surfaces (500 hPa, 700 850 hPa 925 hPa) over North China 2020. The straightforward multimodel ensemble mean (M...

dust is a common atmospheric phenomenon in iran especially in central arid regions.  this severely affects environment as well as resident’s health. among the results of this phenomenon are respiratory diseases, bash radiation, accelerated soil erosion, desertification and degradation of ecosystems. some dusts are originated from local desert conditions but adjacency to neighboring countries de...

The features of the development cyclones, which can cause generation storm surges, depending on trajectory and parameters cyclones in Azov-Black Sea basin, are investigated. An extreme surge Taganrog Bay mouth Don River September 24, 2014 was taken as a test situation. Based data meteorological observations at posts ERA5 re-analysis atmospheric pressure, wind speed relative vorticity level 850 ...

By using the daily average wind speed and precipitation data of 125 stations in Jiangsu Anhui Provinces China from 1961 to 2020 monthly NCEP/NCAR reanalysis data, interannual variation characteristics its possible reasons spring compound extreme events Jiangsu–Anhui region were discussed. Results show that generally present a lesser distribution south more north. The occurring (north) 32° N are...

introduction shamal winds recognized as a climate regime with a common occurrence in the persian gulf makes periodically adverse weather conditions in this region. among the phenomena occurring under the influence of shamal wind, we can mention dust storms, low-level winds and turbulent marine conditions (rao, 2003). shamal winds are categorized into two types, winter shamal and summer shamal. ...

Regarded as one of the most dangerous types natural disaster, tropical cyclones threaten life and health human beings often cause enormous economic loss. However, intensity forecasting cyclones, especially rapid intensification forecasting, remains a scientific challenge due to limited understanding regarding change process. We propose an automatic knowledge discovery framework identify potenti...

This paper addresses various characteristic features associated with the hydration of the tropical upper troposphere and lower stratosphere (UTLS) in association with the boreal monsoonal convective activity occurring over three different tropical regions viz. Asian region, American region and African region. Analysis of water vapor mixing ratio (WVMR) data obtained from AURA MLS (v3.3), ISCCP ...
