Montana Climate Office in Montana Legislature's August 2014 Interim Newsletter (see page 10)

The Montana Climate Office provides high-quality, timely, relevant, and scientifically based climate information and services to Montanans. As Montana's official climate data stewards, we strive to provide information for specific sectors of interest by either geography or industry, and assist stakeholders in adapting climate products to their needs.

Weather or Climate?

The difference between weather and climate is a measure of time. To understand climate at a given place requires synthesizing the variation in weather over relatively long periods of time. Weather is the day-to-day interaction of factors like temperature, humidity, precipitation, cloudiness, visibility, and wind. Scientists pursue an understanding of climate trends or cycles of variability and place those phenomena into the bigger picture of possible longer term changes in our climate.
