The HYPE model has been set up for the Arctic region to evaluate recent changes in the region and to simulate future changes.

About the project

The Arctic region has experienced changes in temperature and it is expected that this region will be largely affected by climate change. The hydrological changes will have major impact of sea circulation, ice covers, biology and infrastructure in the region.

The HYPE model has been set up for the Arctic region to evaluate recent changes in the region and to simulate impact of future climate. 

About the Arctic-HYPE model system

The Arctic-HYPE model domain has a size of 23.3 million km2 (Greenland is not yet included) and include some very large rivers, of which Ob, Yenisei, Lena, MacKenzie, Yukon, Nelson, Severnaya Dvina, Indigirka, Pechora and Kolyma, are the 10 largest, see figure 1.

Arctic-HYPE is a model application set up to calculate hydrological variables (e.g. runoff, discharge, snow depth, glacier distribution, groundwater level) for the entire Arctic Region (defined here as all land areas with runoff to the Arctic Ocean, except for Greenland).
The work to set up this model started in 2012 and since the first version the model has been upgraded with both new process descriptions such as glacier- and PET algorithms and new input data, such as soil depths, glacier extension and observed hydrological variables. The model is entirely developed from open databases, see table 1.

Future work

The HYPE code is continously developed as well as the Arctic-HYPE set-up. The model will be used within the Arctic-HYCOS of WMO to simulate ungauged basins, evaluate observations and interpolate when observed values are missing in time-series.
