Weather ≠ Climate?

31 May

Weather ≠ Climate we are told, time and time again.

In fact Climate is an average of weather recordings over time:

Climate ≈ Weather/Time

Or more correctly:

Weather/Time → Climate as Time → ∞

(Weather over time tends to climate as time tends to infinity).

However time is continuous. So this means that weather over time in short periods does indicate short climate states, however inaccurate in comparison to longer time periods.  This suggests that the original proposition is a misrepresentation.

In fact:

Climate ≈ Weather for small time, would be a better statement.

    I disagree. I would say that climate doesn’t exist over short periods of time. Just as speed doesn’t really exist at any given point in time or space, because you need to have two points to compare. You can’t say that weather is climate, only whether or not the weather is usual or unusual for the climate.

      Does time exist in points? Or in periods? Can’t any point in time be subdivided into smaller units of time down to atomic time units?
