Abstract
The derivation of the long daily temperature record from St. Petersburg is described. Some alterations in observation times, procedural changes and possible site moves are adjusted for, but correction for a probable urbanization influence of up to 1.0°C over the 20th century is not attempted, The daily temperature series is then analysed for long-term changes in the numbers of daily extreme values. Although the 20th century shows a clear trend to lower numbers of extremely cold days, warm day counts indicate a much smaller change. The 1990s have been exceptionally warm but only just exceed some earlier decades such as the 1930s.
