Short-term temporal variability of surface wind speed over central Spitsbergen, Svalbard
Original language description
The aim of the study is to use yearlong measurement in central Spitsbergen to 1) analyse the temporal variation in the near-surface wind field and 2) evaluate the relationship between large-scale weather systems and the wind speed among different locations within the fjord. We focused primarily on the analysis of the near-surface wind characteristics measured in Petuniabukta and Mimerbukta close to Russian settlement Pyramiden (Fig. 1) during 2013. Two automatic weather stations were located on the raised marine terrace at altitudes from 15 and 20 m a. s. l. Pattern of atmospheric circulation was identified using 850 hPa geopotential heights and geostrophic winds. Moreover, Weather Research and Forecasting (WRF) mesoscale model outputs (Skamarock et al. (2008) with the Quasi-Normal Scale Elimination parameterization scheme with 1-km horizontal resolution of the inner domain were used for identification of local circulation systems. We found that the large-scale flows were often modified by channelling and drainage effects accompanied by an increase on local wind speed in the coastal zone. Moreover, the occurrence of low level jets were identified and successfully simulated by the WRF model.
