Well it depends on what its affecting. If it's the people then the people will be more melancholy than the people with sunny weather. If it's the actual land then the gloomy rainy weather will probably make a swamp, everglades, or a marsh, while the sunny weather will make forrests, woods, or grasslands. This is a very broad question so as long as your answer makes logical sense you should be fine
If you live in a state with dark, rainy weather, it would be cold and extremely wet all the time. In a state with sunny weather, it would be hot and dry.
