Open AccessUniversal thermal climate index in the Arctic in an era of climate change: Alaska and Chukotka as a case study
The modern unambiguous climate change reveals in a rapid increase of air temperature, which is more distinctly expressed in the Arctic than in any other part of the world, affecting people health and well-bein...

Evaluation of Community Climate System Model soil temperatures using observations from Russia
Soil temperatures simulated by the fully coupled Community Climate System Model (CCSM) version 3.0 are evaluated using three gridded climatologies (1951–1980, 1961–1990, 1971–2000) based on data from more than...

Atmospheric response to soil-frost and snow in Alaska in March
A hydro-thermodynamic soil-vegetation model including soil freezing/thawing (soil-frost) and snow-metamorphism has been integrated into the PennState/NCAR Mesoscale Meteorological Model MM5 in a two-way couple...

Recent temperature trends in the Antarctic
Doran et al. reply — Turner et al. do not find fault with our main focus — the rapid ecological response to recent cooling in the McMurdo Dry Valleys. The essence of their comment is that the spatial interpolatio...

Observational Evidence of Recent Change in the Northern High-Latitude Environment
Studies from a variety of disciplines document recent change in the northern high-latitude environment. Prompted by predictions of an amplified response of the Arctic to enhanced greenhouse forcing, we present...

Atmospheric Climate Models: Simulation of the Arctic Ocean Fresh Water Budget Components
Atmospheric climate models driven by prescribed sea surface temperature (SST) and sea-ice simulate the two major components of the ocean fresh water budget (FWB): the direct input of fresh water as precipitati...

Global Atmospheric Circulation Patterns and Relationships to Arctic Freshwater Fluxes
The large-scale atmospheric circulation affects the Arctic Ocean’s freshwater fluxes in at least three ways. First, the circulation controls the direct fluxes of precipitation (P) and evaporation (E) at the Ar...

The effects of precipitation and river runoff in a coupled ice-ocean model of the Arctic
A coupled ice-ocean model of the Arctic is developed in order to study the effects of precipitation and river runoff on sea ice. A dynamic-thermodynamic sea ice model is coupled to an ocean general circulatio...

Characteristics of Arctic synoptic activity, 1952–1989
Synoptic activity for the Arctic is examined for the period 1952–1989 using the National Meteorological Center sea level pressure data set. Winter cyclone activity is most common near Iceland, between Svalbard...

A regional model for studies of atmosphere-ice-ocean interaction in the western Arctic
Asa step in the development of a fully coupled regional model of the atmosphere-ice-ocean system, atmospheric and sea ice models have been adapted to a western Arctic domain centered on the Bering Strait. Late...

Variability in sea-ice thickness over the North Pole from 1977 to 1990
CHANGES in the thickness of polar sea-ice have the potential to provide a signal of climate change, but attempts to identify trends must take into account the range of natural variability. Here we present an a...

Sensitivities of numerical model forecasts of extreme cyclone events
A global forecast model is used to examine various sensitivities of numerical predictions of three extreme winter storms that occurred near the eastern continental margin of North America: the Ohio Valley bliz...

Pulse propagation theory for the Čerenkoa free-electron laser
In this paper we consider the problem of the optical-pulse propagation in a Čerenkoa-FEL. We show how the theory already developed for the undulator FEL can be adapted to the present case. Results relative to ...

Asymptotic theory of the global error and some techniques of error estimation
The error of the approximate solution obtained by discretising a functional equation can be shown under certain conditions to possess an asymptotic expansion in terms of some parameter which is usually a repre...
