A simple model using once-daily US National Centers for Environmental Prediction/US National Center for Atmospheric Research (NCEP/NCAR) re-analysis upper-air values estimates winter balance, summer balance and net balance at ten glaciers in Norway and two in Sweden with 0:37 r2 0:90: The October–May Arctic Oscillation (AO), an index of sea-level pressure (SLP) in the Northern Hemisphere, corre...

Abstract. The amount and spatial extent of Greenland Sea (GS) ice are primarily controlled by the sea export across Fram Strait (FS) local seasonal formation, melting, dynamics. In this study, using satellite passive microwave observations, atmospheric a coupled ocean-sea reanalysis system, TOPAZ4, we show that both oceanic circulation in Nordic Seas (NS) act tandem to explain SIC variability s...

Abstract. Cold surge (CS) is considered a favorable weather process to improve air quality and widely recognized. However, there no detailed study on the differences in dispersion ability of different types CSs relation haze days eastern China (HDEC). This paper uses hierarchical clustering algorithm classify cool-season (November February following year) across into blocking wave-train compare...

runoff simulation is a vital issue in water resource planning and management. various models with different levels of accuracy and precision are developed for this purpose considering various prediction time scales. in this paper, two models of ihacres (identification of unit hydrographs and component flows from rainfall, evaporation and streamflow data) and ann (artificial neural network) mode...

The simulation of Arctic sea ice and surface winds changes significantly when CCSM3 resolution is increased from T42 ( 2.8 deg) to T85 ( 1.4 deg). At T42 resolution, Arctic sea ice is too thick off the Siberian coast and too thin along the Canadian coast. Both of these biases are reduced at T85 resolution. The most prominent surface wind difference is the erroneous North Polar summer anticyclon...

Changes in the sea surface heights (SSH) and geostrophic transports in the NE Pacific are examined during the 1997–1998 El Niño using altimeter data, sea level pressure (SLP) fields, proxy winds and satellite sea surface temperature (SST). Most of the signal occurs along the boundaries of the basin from Panama to the Alaska Peninsula. Changes in the SSH and alongshore transports along the bound...

Dust storm is a natural hazardous phenomenon that affects arid and semi-arid regions of the world same as Iran. The present research aims to investigate formation synoptic patterns pervasive dust storms (PDSs) in southwestern For this purpose, daily data visibility less than 1000m 16 stations (Ilam Khuzestan provinces) were reviewed during 2004–2017, 59 PDSs with more 2 days duration (overlappe...

Measurements of wind strength and direction abstracted from European ships’ logbooks during the recently finished CLIWOC project have been used to produce the first gridded Sea Level Pressure (SLP) reconstruction for the 1750–1850 period over the North Atlantic based solely on marine data. The reconstruction is based on a spatial regression analysis calibrated by using data taken from the ICOAD...
