Sixty-Day Temperature Persistence At Five-Day Intervals For Minneapolis-St. Paul, Charles J. Fisk
Sixty-Day Temperature Persistence At Five-Day Intervals For Minneapolis-St. Paul, Charles J. Fisk
Journal of the Minnesota Academy of Science
The annual course of 60-day temperature persistence for Minneapolis-St. Paul, Minnesota is examined at five -clay intervals for the last 110 years. Results show maximum persistence for the 60-day periods February 20 to April 20 and June 25 to August 23. Minimum persistence is observed for sequences whose midpoints correspond to late April, late September and mid-November. This suggests the presence of a single favored regime-breaking period for the winter to summer transition and two such periods for summer to winter.
Successive Month Temperature Relationships For Twin Cities, 1820-1974, Charles J. Fisk
Successive Month Temperature Relationships For Twin Cities, 1820-1974, Charles J. Fisk
Journal of the Minnesota Academy of Science
Using a five category classification scheme of mean monthly temperatures, the long-term ( 1820-1974) relationships between Minneapolis-St. Paul successive months' temperatures were analyzed . Results show predominance of two-month persistence over two-month breaks in classification . Strong above norma11 and below normal persistence tendencies are revealed, particularly in summer and early fall sequences. In contrast, two month breaks in classification appear in spring and fall sequences. This emphasizes the uneven progression of warming (cooling) that occasionally occurs between winter (summer) and summer (winter). Overall, strongest month-to-month association was for August-September, weakest for April-May .
