The relationship between winter climate extremes across the northeasternUnited States and adjacent parts of Canada and some important modes of climate variability are examined to determine how these circulation patterns are related to extreme events. Linear correlations between 15 extreme climate indices related to winter daily precipitation, maximum and minimum temperature, and three dominant ...

Amidst stormy atmospheric circulation, there are prominent recurrent patterns of variability in the planetary circulation, such as the Antarctic Oscillation (AAO), Arctic Oscillation (AO) or North Atlantic Oscillation (NAO), and the Pacific–North America (PNA) pattern. The role of the synoptic eddy and low-frequency flow (SELF) feedback in the formation of these dominant low-frequency modes is ...

Abstract The Haihe River basin is the main grain production base and highland of economic strategic development in China. Based on daily meteorological data during 1960–2020, characteristics drought evolution were analyzed by standardized precipitation evapotranspiration index (SPEI). Pearson correlation method cross-wavelet analysis used to explore between SPEI climate factors (global warming,...

In this study, annual and seasonal precipitation trends their connection with large-scale climate indices in the Qinling Mountains (QMs) were investigated using innovative trend analysis (ITA), based on observed monthly data between 1959 2016 from 32 meteorological stations. The results indicated a declining QMs. Seasonally, decreasing was also spring autumn, while increasing summer winter. Spr...

In this work, a novel Silicon on Insulator (SOI) MOSFET is proposed and investigated. The drain and source electrode structures are optimized to enhance ON-current while global device temperature and hot carrier injection are decreased. In addition, to create an effective heat passage from channel to outside of the device, a silicon region has embedded in the buried oxide. In order to reduce th...
