I spend an entire career making forecasts and briefing 3 & 4-star generals and presidents on what computer models said...based on their science and math.
The advantage there is you KNOW within a short amount of time whether or not you were right in your forecasting.
If you're wrong...well, you know...The Weather Forecast That Saved D-Day

Well - that's true MOST of the time - except when I had to make long-range hurricane forecasts to the 4-star and to DHS for planning purposes - or drought forecasts for the fire season.

We did a lot of planning for long-range to help with purchases and exercise planning. That used a lot of the long-range models - and those would sometimes be good - and sometimes crap - and it depended on stuff like MJO - AMO - all sorts of science and seasonalities.
