In spring, rivers at middle and high latitudes in the Northern Hemisphere are prone to ice jams, which threaten safety of hydraulic structures rivers. Heilongjiang Province is located on highest latitude China, starting 43°26′ N reaching 53°33′ N. Rivers freeze winter break up spring. Forecasting break-up date river accurately can provide an important reference for command, dispatch, decision-making flood preventing shipping. Based observed series from seven representative hydrological...

Abstract The reliability of conventional drought indices is increasingly called into question as the stationarity hydrologic series undergoes significant alterations and becomes irreversibly impacted by environmental changes. In extant literature concerning Non‐Stationary Standardized Precipitation Evapotranspiration Indices (NSPEIs), researchers typically construct linear models incorporating location parameters covariates; however, simultaneous consideration both scale has been...

Summary The records of 2034 beef bulls representing 931 sire families from ten breeds tested at Ellerslie Test Station, Alberta, Canada, 1974 to 1987 were analyzed investigate the feasibility selecting a shorter test period and study associations between growth rate in standard 140‐day that periods for accurate evaluation potential young station. results indicated day 28 112 was less affected by herd origin compared with therefore could be considered as short optimum period. Average daily...

The characteristics of the northern and southern modes East Asian winter monsoon (EAWM) their relationships with El Niño‐Southern Oscillation (ENSO) are further investigated in this paper using reanalysis data. results demonstrate that mode shows strong inter‐decadal variations, whereas is marked by noticeable inter‐annual variations. west–east pressure gradient plays a leading role influencing mode, both north–south gradients have significant impacts on mode. two closely related, but...

This study aimed to determine the influence of time and precipitation as covariates on flood frequency distribution in Songhua River tributaries under nonstationarity assumption investigate possibility nonstationary models’ application river management scope demarcation work. Nonstationary analysis (NS-FFA) was conducted three typical basins (in Northeastern China) based generalized additive models for location, scale, shape (GAMLSS), stationary used a comparison. Under stationarity...

As the largest trading country in world, China lags behind developed countries terms of development level. There is a technological gap, lack innovation and often suffers from technical barriers to trade. Whether direct losses, indirect losses or degree impact, TBT has exceeded traditional trade become most frequent difficult measures that export enterprises Jiangsu face after exchange rate tariff. How correctly view reasonable treatment on impact Province, foster strengths circumvent...
