in order to recognize isfahan weather types, in this research 22 variables including temperature, precipitation, atmospheric humidity and wind were studied in isfahan synoptic station from dey,11th,1339(january,1st,1960) to dey,11th,1383 (december,31st,2004). a cluster analysis on the euclidean distance of standardized matrix of data and linking days on the basis of ward method showed that isfa...

The hydrometeorology of the Amazon basin in the ERA-40 reanalysis for 1958–2001 is compared with observations of precipitation, temperature, and streamflow. After 1979, the reanalysis over the Amazon has a small cool bias of the order of 0.35 K, and a small low bias of precipitation of the order of 0.3 mm day . In the early years (1958–72), there is a large upward drift in reanalysis precipitat...

Several multi-decadal simulations have been carried out with the new version of the CCSM climate model. This paper reports an analysis of the land component of these simulations. Global annual averages over land appear to be within the uncertainty of observational data sets but the seasonal cycle over land of temperature and precipitation appear too weak. These departures from observations appe...

The preparation and properties of polyvinylpolypyrrolidone (PVPP) and silica gel and the mechanisms by which they stabilize beer are discussed. In stabilized beer, chill stability was associated with lower protein sensitivity to precipitation with tannins. Approximately 60% of the proteoses were of low molecular weight (<10,000 daltons). The most acidic of these proteoses were the least stable ...

in this research, effect of north atlantic oscillation and sea surface temperature (sst) of atlantic ocean on precipitation and temperature of lorestan province and its effect on occurrence of drought and wet in this province were investigated. so, data of teleconnection indices used as an index for determination of fluctuations of pressure and sea surface temperature in atlantic ocean, amount ...
