Evaluation of Satellite Images of Snow Cover Areas for Improving Spring Flood in the Hbv-model
For the hydro power companies it is of major importance to know the magnitude of the spring flood. Hence, the amount of snow is crucial for forecast modelling. In mountainous areas with plenty of snow, the meteorological network is often sparse, and they lack direct observations of the snow pack. Therefore, if it is possible to combine satellite snow cover area information with a hydrologic mod...
متن کاملSnow Cover
Snow cover is a layer of snow on the earth’s surface, which is mainly results from snowfalls. The snow cover can be temporary, when a snow melts during several hours or days after its formation, and it can be stable, when it remains for the whole winter or with short interruptions. The snow cover formation on the globe is determined (conditioned) by the geographical zonality, surface relief, an...
متن کاملNorthern Hemisphere spring snow cover variability and change over 1922–2010 including an assessment of uncertainty
An update is provided of Northern Hemisphere (NH) spring (March, April) snow cover extent (SCE) over the 1922–2010 period incorporating the new climate data record (CDR) version of the NOAA weekly SCE dataset, with annual 95% confidence intervals estimated from regression analysis and intercomparison of multiple datasets. The uncertainty analysis indicates a 95% confidence interval in NH spring...
متن کاملDeclining snow cover may affect spring phenological trend on the Tibetan Plateau.
Zhang et al. (1) report that the Tibetan Plateau experienced a continuous advancing start of green-up date (SOS) from 1982 to 2011 based on the merged Global Inventory Modeling and Mapping Studies (GIMMS)based with Moderate Resolution Imaging Spectroradiometer (MODIS) [Système Pour l’Observation de la Terre vegetation (SPOTVGT)]-based SOSs. It challenged the previous contention that plants over...
متن کاملDetection and Attribution of Observed Changes in Northern Hemisphere Spring Snow Cover
Significant declines in spring Northern Hemisphere (NH) snow cover extent (SCE) have been observed over the last five decades. As one step toward understanding the causes of this decline, an optimal fingerprinting technique is used to look for consistency in the temporal pattern of spring NH SCE between observations and simulations from 15 global climate models (GCMs) that form part of phase 5 ...
