摘要: Abstract One of the hypothesized effects global warming from increasing concentrations greenhouse gases is a change in frequency and/or intensity extratropical cyclones. In this study, winter frequencies and intensities cyclones Northern Hemisphere for period 1959–97 are examined to determine if identifiable trends occurring. Results indicate statistically significant decrease midlatitude cyclone increase high-latitude frequency. addition, storm has increased both high midlatitudes. The changes correlate with temperature support hypotheses that may result northward shift tracks Hemisphere.
