Passing of cyclones over the Northern Atlantic and Northern Pacific oceans is frequently accompanied by sudden changes for deterioration of weather conditions due to storm winds and high waves. Landfalling cyclones cause gross economic losses due to strong winds and heavy precipitation. Estimates of wind and sea surface roughness fields in particular cyclones and total contribution of the cyclones to heat and water vapor fluxes during cold seasons are topical issues. Satellite remote sensing data are the most suitable for their solving. Results of comprehensive analysis of satellite measurements carried out over several cyclones in the Pacific Ocean during cold seasons 2009–2011 are given. High wind zones with wind speed exceeding 20–25 m/s were determined by processing Aqua AMSR-E data. They were located mainly in southwest sector of cyclones. Proposal was demonstrated to use these zones for tuning and validation of wind speed retrieval algorithms.
