in highland watersheds, runoff generated by snow melting plays an important role in stream water supply. srm (snowmelt runoff model) is a hydrologic model which simulates and predicts daily flow in mountain watersheds dominated by snow melting process. the srm is based on the degree-day procedure which, is a widely used method but does not consider physical factors. in the current research, the...

Outgoing longwave radiation (OLR) data are one of the key factors in studying balance earth–atmosphere system East Asia. It is great significance to explore influence on OLR. This paper processes nearly 19 years, from September 2002 February 2022, and conducts in-depth research using exponential smoothing method, empirical orthogonal decomposition (EOF), correlation analysis, other methods. We ...

Long-term, accurate observations of atmospheric phenomena are essential for a myriad of applications, including historic and future climate assessments, resource management, and infrastructure planning. In Hawai'i, climate data are available from individual researchers, local, State, and Federal agencies, and from large electronic repositories such as the National Centers for Environmental Info...

Abstract The underlying mechanisms for Arctic sea ice decline can be categories as those directly related to changes in atmospheric circulations (often referred dynamic mechanisms) and the rest (broadly characterized thermodynamic processes). An attribution analysis based on self-organizing maps (SOM) method is performed determine relative contributions from these two types of August–October du...

The radiative forcing of spatially varying carbon dioxide (CO 2 ) concentrations has modified the climate by altering surface energy, water budget, and cycling. Over past several decades, due to anthropogenic emissions, atmospheric CO in whole terrestrial ecosystem have become greater than global mean. relationship between climatic variables net primary production (NPP) can be regulated this sp...

Abstract. The satellite observations unveiled that the July sea ice extent of Arctic shrank to lowest value, since 1979, in 2020 with a major retreat Eurasian shelf seas including Kara, Laptev, and East Siberian seas. Based on ERA-5 reanalysis products, we explored impacts warm moist air-mass transport this extreme event. results revealed anomalously high energy moisture converged into these re...

Abstract This study revealed that the interannual variations of December Bering Sea ice and subsequent February surface air temperature (SAT) over North America are significantly correlated during 2000/01–2020/21, which is not case 1966/67–1999/2000. During reduced generally followed by a meridional dipole pattern in atmospheric circulation America, provides favorable conditions for colder temp...

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 paper presents an analysis by using the methods of Eddy field calculation mean and wavelet maxima to detect seismic anomalies within the outgoing longwave radiation (OLR) data based on time and space. The distinguishing feature of the method of Eddy field calculation mean is that we can calculate “the total sum of the difference value” of “the measured value” between adjacent points, which ...
