Summary Current predictions by international forecast centres and researchers, collected and evaluated by the Sea Ice Drift Forecast Experiment (SIDFEx), suggest that there is a chance that the drift

The team analysed the outcomes of 40 different climate models, which will also be used in the upcoming sixth Assessment Report from the IPCC . The simulations are based on the implementation of variou

In the months of June, July and August, predictions can be submitted on the September sea-ice extent for the Arctic as a whole, or for specific regions. The forecasting methods vary considerably, and

Satellite data shows declining thickness of very old ice The summer melting period was preceded by a relatively mild winter. This year, too, the satellite- and model-based analyses are being complemen

The sixth Assessment Report released by the Intergovernmental Panel on Climate Change (IPCC AR6) projects rapidly shrinking sea-ice cover for the Arctic in the summer months, with an ice-free Arctic a

The difficulty with energy flows in the atmospheric boundary layer is that they depend on so many different parameters. Goal: approach establishes a simple, functional relation between two stability p

There is a general consensus that the warming of the Arctic affects the position and intensity of the jet stream. When the jet stream loops and curls, it opens the door for two opposing northerly or s

Relevance of melt ponds In the Arctic summer, the sea ice melts due to rising temperatures and constant sunlight. When it does, meltwater can gather in pools on the surface, known as melt ponds. These

“May 2018 was the warmest May in Germany since 1881, and the second consecutive month (together with April 2018) with a new record high.” That was the German Weather Service’s review of the current we

The decline in summertime sea-ice in the Arctic is an important indicator for the progressive climate change and its effects on the polar regions of the Northern Hemisphere. Since the advent of contin
