Well, I'm no weather expert and I don't see the point in creating a complete weather simulation in this game, or downloading current weather patterns (the current weather sure doesn't change at 1024x, if you know what i mean). But weather follows certain patterns that can easily be simulated starting from random shifts in temperature (due to the seasons). What we missed so far were weather forecasts based on reports from other ships/uboats.
The main problem in both sh3 and sh4 was that fog was only present in rough sea conditions. That's impossible. You can't have fog in high winds. True, in rough weather visibility can fall to as little as 3 kilometers, and, in really bad conditions with waves of 15 meters or more visibility is the least of your worries as you can't even see beyond the next wave and the rains falls so hard that you can't see ANYTHING. I've seen fog so thick that we couldn't see the the deck just below us at 30 meters, but it was mainly in calm waters near the shore. We could hear people talking on nearby ships at almost 1 kilometer away... very very eerie.
The second problem is that steaming away in rough weather would've been veeeery unconfortable for the crew, next to dangerous. And in the game, even in the worst conditions, you can still use your periscope... well... I'd like to try that in 15 meter waves
