Based on a high-quality dataset of 713 daily precipitation series, changes in daily precipitation events during 1960–2013 were observed in China’s ten largest river basins. Specifically, the amount of precipitation in four categories defined by fixed thresholds and their proportion on total precipitation were analyzed on annual and seasonal time scales. Results showed annual precipitation incre...

many of the meteorological variables such as precipitation, strongly depend on the large scale atmospheric and ocean surface circulations.in the current study, the effect of climatic signals on the average monthly rainfall of the adjacent stations of sheshdeh and gharebolagh area was investigated during the statistical period twenty five years from 1985 to 2009. the regression and neural networ...

We describe the structure and present situation of the Chinese healthcare system and discuss its primary problems and challenges. We discuss problems with inefficient burden sharing, adverse provider incentives and huge inequities, and seek explanations in the structural features of the Chinese healthcare system. The current situation will be further challenged in the future by an aging populat...

Simple stochastic models fit to time series of daily precipitation amount have a marked tendency to underestimate the observed (or interannual) variance of monthly (or seasonal) total precipitation. By considering extensions of one particular class of stochastic model known as a chain-dependent process, the extent to which this ‘‘overdispersion’’ phenomenon is attributable to an inadequate mode...

in this research, for synchronization analysis of black sea high pressure with daily precipitation in iran data base have been created with using the sea level pressure data in reanalysis ii database in national centers for environmental prediction(ncep)/national center for atmospheric research(ncar). temporal resolution of data is daily and spatial resolution is 2.5 㗠2.5 degrees of arc. fram...
