Weather is what is happening with the atmosphere and adjacent biosphere now, in a particular place. Climate is the long-term average of weather data. A 13-year simple moving average – the average of 13 years of weather data – is often used to create a single climate data point.

Weather data is ‘noisy’. It can vary considerably from day to day and location to location. Such variability hides the long-term trends that climate is trying to measure.

We have short memories, sometimes intentionally, so measuring and recording weather data over time is important to give us perspective. This article will give a historical view of weather events by category.
