Climate & Weather: what's the difference?

There are a variety of ways to explain the difference. Here are a few that may shed some light:

Climate is what you expect; Weather is what you get.

Climate is about long-term records, trends and averages;
Weather is the day to day experience.

Climate is the sum or synthesis of all the weather recorded over a long period of time. It tells us the average or most common conditions, or extremes, or counts of events, or frequencies. Weather is a description of conditions over a short period of time - a "snap shot" of the atmosphere at a particular time.

If weather is the watch then climate is the calendar.

What is weather?

The Macquarie dictionary (third edition) defines it as the state of the atmosphere with respect to wind, temperature, cloudiness, moisture, pressure, etc.

It occurs in the troposphere, the layer of air about 10 - 15 km thick, above the surface of the earth.

What causes weather?

The weather is caused by the circulation of the atmosphere which is caused by the unequal heating of the earth's surface by the sun. The rotation of the earth on its axis and its revolution in its orbit around the sun determine the amount of sunlight reaching the earth. In December, when the southern hemisphere is tipped toward the sun, more direct sunlight and long hours of daylight cause warmer weather than in June, when the southern hemisphere is tipped away from the sun. See also 'Meteorology - What is it' for more information.
