Climate Development in Norway During 1900～2100
Annual mean temperature has increased by 0.5 and 1.5degC in different parts of Norway since 1875. In southern Norway, the warmest decades of the last 130 years has occurred near the end of the series. In most parts of northern Norway, the warmest decade occurred around 1930. During the 21st century, the annual temperature is projected to increase by 2.5 to 3.5degC in different parts of Norway. The largest temperature increase is projected in interior regions in Northern Norway. The downscaled scenarios indicate a winter warming of 2.5~4.0degC, with the largest increase in interior parts of Northem Norway. Annual precipitation has increased in all regions in Norway during the last 110. The largest increase (15％ ～20％) is found in north-western regions. The projections indicate that the annual precipitation will increase by 10％～15％ in different regions in Norway. The increase is largest (～20％) along the south-western coast and far north. The largest increase is found for the autumn season; while the summer rainfall in parts of south-eastern Norway may be reduced by up to 15％. For all of Norway daily rainfalls that are considered extreme today will be more common in the future according to the downscaled scenarios.
