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