Why AI Creates Better Weather Forecasts

Показать описание
Weather forecasts have historically relied on physics-based simulations powered by the world’s largest supercomputers. Such methods, called Numerical Weather Prediction models, are constrained by long computational time, and are sensitive to approximations of the physical laws on which they are based.

Deep learning offers a new approach to computing forecasts that stands to revolutionise weather forecasting: rather than incorporating explicit physical laws and attempting to simulate weather in silico, deep learning models learn to predict weather patterns directly from observed data.

Google DeepMind has multiple cutting-edge weather prediction models - covering both short-term (MetNet-3) and medium term (GraphCast) weather forecasts - which are able to generate forecasts faster and with higher accuracy than current industry standards. That means they are able to compute forecasts in as little as just a few seconds, compared with hours, and they can deliver results at both higher temporal and spatial resolutions.

Deepmind open sourcing so much of their research is honestly giving me hope for the future

As a meteorologist, re-analysis of weather phenomena also really helps with this so you can see which models do well with which situations. For example: the NAM takes into account better terrain than the GFS. And we knew this with re-analysis data over time.

Absolutely amazing! THe system could see correlations that no human ever thought of...

Cool! Just heard about GenCast, r we going to get more info about it as well?

I find this interesting as a meteorologist. Guess my job will be obsolete soon. And I can only imagine what might be possible when I say the ecmwf start putting artificial intelligence into their own weather models.

Hasn’t IBM been doing this for a while?
