Abstract : Of the five named tropical cyclones observed during the 1965 season, four achieved hurricane intensity. All four of the tropical cyclones that originated in the Atlantic Ocean achieved hurricane intensity. Although the five 1965 tropical cyclones are only one-half of the seasonal average for the past 30 years, the 30 hurricane days recorded this year are just below the average of the past 10 years. The two tropical cyclones observed during August were the normal amount. That August was a favorable month for tropical cyclone formation was indicated by positive height anomalies in the north and negative height anomalies over the tropical regions. Conditions became less favorable during September and the two tropical cyclones observed were two less than normal. The negative height anomaly over northeastern North America and the corresponding positive height anomaly over the northwestern portion of the continent was similar to the pattern associated with minimal tropical cyclone activity. By October, the westerlies had dipped far south into the Gulf of Mexico and the western North Atlantic and the one tropical cyclone observed was again below the normal of two. It is interesting to note that the tropical air was slightly cooler than normal during the 1965 tropical cyclone season.
