Frost Free Period 1971-2000

Description

The data represents the frost-free period in Alberta over the 30-year period from 1971 to 2000. A 30-year period is used to describe the present climate since it is enough time to filter out short-term fluctuations but is not dominated by any long-term trend in the climate. The frost-free period is the number of days between the last date of 00C in the spring and the first date of 00C in the fall. Frost free periods in Alberta vary from 125 days in the south to less than 85 days in higher elevation, non-agricultural areas.The frost-free period is presented as days above 0&deg.C in the following classes: less than 85, 85 to 95, 95 to 105, 105 to 115, 115 to 125 and greater than 125. This resource was created using ArcGIS.

Usage Considerations

Provides users with representation of the frost-free period as the number of days between the last date of 00C in the spring and the first date of 00C in the fall. The data is suitable for indexing and analysis purposes. The frost-free provides a measure of the period during which plant growth should occur uninterrupted by frost, and it provides a way to compare growing conditions within the province. When selecting new crop types and varieties, producers consider climate characteristics including the length of the frost-free period and the expected date of fall frost. It is important information for producers for planning purposes, indication where the advantages of growing a particular crop may outweigh the risk of occasional frost damage. The yield potential of some crops is closely related to the growing season length. Generally, for the production of marketable grain crops, the frost-free period to be greater than 100 days.
