Interpretive Summary: Research conducted across the Great Plains has shown precipitation and temperature are the main factors affecting plant growth and development. A climate diagram was constructed with long-term (96-year) climate records from Miles City, Montana. The diagram describes the climate of the area. Maximum precipitation occurs in May and June. Greater than 0.8 inches occurs during April, July, August, September, and October and less than 0.8 inches occurs during January, February, March, November, and December. Monthly average temperatures are warmer than 68 F in July and August. Average minimum temperatures are below freezing in January, February, March, November, and December. Absolute minimum temperatures are below freezing in April, May, September, and October, or in other words freezes often occur during these months. Climate diagrams allow comparisons of potential periods of vegetation production among different geographical areas. However, we also need to know the plant species composition for each area. Remember some plant species such as western wheatgrass (cool season) grow better in cooler temperatures and others such as blue grama (warm season) grow better in warmer temperatures.
