  1. 1. Evaluation of the ERA5-Land dataset for estimation of soil moisture in the permafrost region

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Alberta van Gent; [2023]
    Keywords : Soil moisture; ERA5-Land; International Soil Moisture Network ISMN ; permafrost region;

    Abstract : The permafrost region covers a vast area of land surface on the northern hemisphere,storing large amounts of carbon. Unfortunately, climate warming leads to permafrostthaw altering the hydrothermal state of permafrost soils. Due to the remoteness of thepermafrost region, access to field measurements is restricted.

  3. 2. Polar mesoscale cyclones in ERA5 and CARRA

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Zhaohui Cheng; [2023]
    Keywords : polar mesoscale cyclones; polar lows; ERA5; CARRA;

    Abstract : Polar mesoscale cyclones (PMCs) are low-pressure systems that form in polar regions. Their small size and short lifespan pose challenges for coarse resolution models in capturing PMCs and their associated air-sea mass and energy transfer. To address the influence of resolution on PMCs, a comparison between a higher resolution dataset (CARRA with 2. READ MORE

  4. 3. Mesoscale precipitation systems in the Tibetan Plateau region as represented by global reanalysis, regional downscaling and satellite data between 2001 - 2016

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Benjamin Holmberg; [2022-09-01]
    Keywords : Tibetan Plateau; monsoon; westerlies; mesoscale; convection; precipitation; climate modelling; global reanalysis; regional downscaling; spatial resolution; re-initialization; spectral nudging; convective parameterization;

    Abstract : The Tibetan Plateau (TP) is one of the world’s most important water towers. Convective precipitation systems play an important role by providing freshwater for the highly densely populated downstream regions, but they can also cause hazardous floods. READ MORE

  5. 4. Analysing seasonal snow cover trends and patterns on Svalbard

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Dhruv Maniktala; [2022]
    Keywords : snow cover; snow disappearance; snow onset; snow-free duration; CARRA; Svalbard;

    Abstract : Rapid warming in the Arctic is highly impacting the cryosphere in the region, causing melting of the sea ice, retreat of glaciers and reduction in the snow cover. If suffering further temperature increase, the albedo of the region would reduce due to higher absorption of the solar radiation in snow-free areas. READ MORE

  6. 5. Compound Extreme Wind and Precipitation Events in Europe

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Elisabet Johansson; [2021]
    Keywords : compound extremes; North Atlantic Oscillation; extreme precipitation; extreme wind; sammanfallande extremväderhändelser; extrem nederbörd; extrem vind; Nordatlantiska Oscillationen;

    Abstract : The simultaneous occurrences of several extreme events, known as compound extremes, are often associated with greater impact than univariate extremes. Flooding and windstorms are widespread hazards in Europe which can lead to severe property damage and fatalities. READ MORE
