Climate normals for Minneapolis, 1971 - 2000
Historically, three consecutive decades of weather observations have been used to describe climate

Now anticipating release of 30-year Climate Normals for 1981 – 2010
For Minneapolis, January minimums have increased by almost 3°FJuly maximums have decreased by about 0.5°F
Weather is what’s happening outside your window
Atmospheric conditions that you can see, feel, or measure are weather.
Climate can be described by words or numbers, but you cannot touch it

Dynamic normals based on fewer than 30 years are also being used to make comparisons

And though climate is often characterized by temperature alone…
Climate is really a multi-faceted concept
Decide if each of the following phrases describes climate or weather.

NOAA also supports networks of instruments on buoys. These gather data from the depths of the ocean and at its surface
Human efforts facilitate and complement automated data collection
We launch weather balloons to learn about conditions in the lower atmosphere
Balloons and rockets carry data-gathering instruments into the upper atmosphere
and instruments on satellites monitor Earth’s status from orbit
From the bottom of the ocean to the top of the atmosphere, we monitor Earth’s climate system
