Question

Why is it difficult to predict the weather

Answer 1

The day-to-day conditions of the atmosphere at a place with respect to temperature, pressure, humidity, rainfall, etc. constitute the weather of a place. Weather is never constant anywhere. The weather at a place changes even over short periods of time. Therefore, it is difficult to predict weather of a place.

The short answer:

1. We lack the ability to continuously observe the atmosphere and assimilate these data.
2. Our ability to analyze these data are severely limited by inadequate computing speed and storage.
3. We lack a complete understanding of the physical processes operating in the atmosphere and elsewhere which contribute to what we know as our weather.
