In the UK, every spring, we are subjected to the April Showers. As the old English proverb goes:

“March winds and April showers bring forth May flowers”

So why do we see such specific weather in April?

The reasoning is fairly simple:

  1. The sun is starting to get warmer due. This is due to the Earth’s Rotational Axis shifting in such a way that the UK is more parallel with the suns rays than it is in winter.
  2. The warmer sun allows pockets of warm air to develop at ground level.
  3. These pockets of warm air rise rapidly creating an unstable atmosphere.
  4. The rising warm air pulls moisture up into the atmosphere which then cools as it rises causing moisture to coalesce and condense out of the air (see Ideal Gas Law)
  5. This then falls as rain.
  6. The fast the rising air and the more of it, the more intense the shower.
