Bjerknes Centre for Climate Research–combining past,present and future climate change
Bjerknes Centre Climate Research climate change
2009/12/3
Climate change is one of the most pressing issues facing the world today. With increasing levels of greenhouse
gases in the atmosphere, climate changes will play an increasing role for society in the...
Ecosystem effects of CO2 concentration：evidence from past climates
Ecosystem effects past climates CO2 concentration
2009/12/3
Atmospheric CO2 concentration has varied from minima of 170–200 ppm in glacials to maxima of 280–300 ppm in the recent interglacials. Photosynthesis by C3 plants is highly sensitive to CO2 concentrat...
Two-dimensional reconstruction of past sea level (1950–2003) from tide gauge data and an Ocean General Circulation Model
past sea level Ocean General Circulation Model Two-dimensional
2009/12/3
A two-dimensional reconstruction of past sea level is proposed at yearly interval over the period 1950–2003 using tide gauge records from 99 selected sites and 44-year long (1960–2003) 2°×2° sea level...
Three exceptionally strong East-Asian summer monsoon events during glacial times in the past 470 kyr
Chinese loess East Asian monsoon
2009/12/3
Chinese loess sequences are interpreted as a reliable record of the past variation of the East Asian monsoon regime through the alternation of loess and paleosols units, dominated by the winter and su...
Climate reconstruction from pollen and δ13C records using inverse vegetation modeling – Implication for past and future climates
Climate reconstruction future climates
2009/12/3
An improved inverse vegetation model has been designed to better specify both temperature and precipitation estimates from vegetation descriptions. It is based on the BIOME4 vegetation model and uses...
Simulations of climate effects on water temperature, dissolved oxygen, and ice and snow covers in lakes of the contiguous U.S. under past and future climate scenarios
Simulations of climate effects on water temperature, dissolved oxygen, and ice and snow covers in lakes of the contiguous U.S. under past and future climate scenarios
2014/4/17
Daily water temperature, dissolved oxygen (DO) profiles, and ice and snow covers (where applicable) were simulated for 27 types of small lakes (up to 10 km2 surface area) at 209 locations in the conti...
Magnetohydrodynamic Transient Convection Flow past a Vertical Surface Embedded in a Porous Medium with Oscillating Temperature
Natural convection Magnetohydrodynamic flow Porous medium Oscillating temperature
2009/10/9
This paper presents an analytical study of the transient hydromagnetic and thermal behaviour of free convection flow past a vertical plate embedded in a porous medium. The governing equations are solv...
Snow Cover Variation in the Past 45 Years (1959-2003) in the Tianshan Mountains, China
snow cover Tianshan Mountains climate change North Atlantic Oscillation
2009/8/28
Meteorological data at 17 weather stations in the Tianshan Mountains from 1959 to 2003 were analyzed to explore the variations in temperature and snow cover. The abrupt change test for snow depth was ...
Three-dimensional numerical simulation of the flow past a circular cylinder based on LES method
LES method three-dimensional flow past circular cylinder hydrodynamic characteristics
2011/9/13
The hydrodynamic characteristics of a rigid, single, circular cylinder in a three dimensional, incompressible, uniform cross flow were calculated using the large-eddy simulation method of CFX5. Soluti...

2009/5/14
The paper reviews critical processes for the land-sea fluxes of biogenic elements (C, N, P, Si) in the Baltic Sea catchment and discusses possible future scenarios as a consequence of improved sewage...
Water discharge and sediment flux changes over the past decades in the Lower Mekong River：possible impacts of the Chinese dams
suspended sediment concentration low water levels Lower Mekong River
2009/5/13
The Lower Mekong River has witnessed extremely low water levels over the past few years. There is speculation that the changes are a consequence of the construction and operation of the Chinese casca...
