In a previous paper, we have shown that long-term cloud and solar observations (1965–2013) in Bergen, Norway (60.39°N, 5.33°E) are compatible with a largely cloud dominated radiative climate. Here,… (More)
The observed variability of shortwave (SW) irradiance, clouds and temperature and the potential connections between them is studied for the subarctic site Bergen (60.4°N, 5.3°E), located on the… (More)
A strategy is suggested for presenting high-resolution temperature maps based on projections from large multi-model ensembles with minimal requirement of data space. This ability to reduce data… (More)
We test a strategy for downscaling seasonal mean temperature for many locations within a region, based on principal component analysis (PCA), and assess potential benefits of this strategy which… (More)
 The absorption of shortwave (SW) radiation by clouds is a topic surrounded by contradictory reports and controversy. Some studies have shown large discrepancies between observed SW absorption and… (More)
AbstractObservations have revealed strong variability of shortwave (SW) irradiance at Earth’s surface on decadal time scales, referred to as global dimming and brightening. Previous studies have… (More)
This Perspective considers how to better use and explore climate model output, considering whether statisticians can help achieve better design of ensembles and interpretation of output.
2. The concern about whether the statement that “heavy precipitation will become more severe in already wet areas in the future“ holds globally in all such regions is indeed valid. We do not have the… (More)
AbstractA method for empirical–statistical downscaling was adapted to project seasonal cyclone density over the North Atlantic Ocean. To this aim, the seasonal mean cyclone density was derived from...
Abstract. We present estimates of future 20-year return values for 24 h precipitation based on multi-model ensembles of temperature projections and a crude method to quantify how warmer conditions… (More)
