A new advanced microwave humidity sounder FY-3D MWHS2 radiance has been assimilated under the clear-sky conditions by implementing its data assimilation interface. The case of tropical storm Ampil in 2018 is selected to address effectiveness new-built module initialization and forecast typhoons. Apart from experiment assimilating both Global Telecommunications System (GTS) data, an with only GT...

in this study, frequency and location of frontogenesis related to heavy rainfall have been analyzed using environmental to circulation approach. based on the threshold of upper 99 percent, we selected 125 days of the super and overall heavy rainfall from irimo data base (included 1437 synoptic, climatic and rain gage stations from 21/3/1961 up to 31/12/2004). frontogenesis frequency and their l...

Interpreting the results of a high-level clouds (HLCs) lidar study requires comparison with vertical profiles meteorological quantities. There are no regular radiosonde measurements quantities in Tomsk. The nearest aerological stations several hundred kilometers away from and perform only few times day, whereas experiments performed continuously throughout day. To estimate conditions at HLC alt...

The meteorological conditions during the period of spring transition over the Middle East and the Persian Gulf and adjacent land area is investigated. Monthly and seasonal variations of large-scale atmospheric patterns and wind aloft features at different levels were drawn from data collected from the National Centers for Environmental Prediction and National Center for Atmospheric Researches. ...

Satellite data from the Atmospheric Infrared Sounder (AIRS) is analyzed to examine regions of the upper troposphere that are supersaturated: where the relative humidity (RH) is greater than 100%. AIRS data compare well to other in situ and satellite observations of RH and provide daily global coverage up to 200 hPa, though satellite observations of supersaturation are highly uncertain. The clim...

[1] We present direct radiometric observations of aerosol radiative forcing during the ACE-Asia experiment (March and April of 2001). The observational analysis is based on radiometer data obtained from the NOAA ship Ronald H. Brown, and shipboard measurements of the aerosol chemical and scattering properties are used to construct a model of the aerosol optical properties for use in radiative t...

Within this study we present a robust method for generating precipitation time series for the Anas catchment in North Western India. The method employs a multivariate stochastic simulation model that is driven by a time series of objectively classified circulation patterns (CPs). In a companion study (Zehe et al., 2006) it was already shown that CPs classified from the 500 or 700 Hpa levels are...

[1] We make use of microwave measurements of the tropical free tropospheric relative humidity (FTH) to evaluate the extent to which the water vapor distribution in four general circulation models is faithful to reality. The comparison is performed in the tropics by sorting the FTH in dynamical regimes defined upon the 500 hPa vertical velocity. Because microwave radiation penetrates non-rainy a...

Results 342 of the patients were male and 42 were female. Mean age was 21.9±0.5 years old. Month (p=0.563), season (p=0.264) and weather (p=0.327) were not associated with the occurrence rate of SPM. Mean temperatures, mean humidity, mean wind velocities of SPM occurrence day and non-occurrence day were 12.4±10.5°C : 12.8±10.5° C (p=0.504), 61.8±15.5% : 60.9±15.0% (p=0.372), 2.6±1.0m/s : 2.6±2....
