Haze robs what's behind it of detail, contrast and colour. The best you can hope for is to reduce the impact of haze. The usual tools are the contrast and clarity sliders, lowering the Highlights and using the HSL tool to slightly darken and desaturate blue. Some of these don't make good global adjustments so the best option is to make a selection of the mountains and apply adjustments locally.

It's easy to go from one extreme to another so you should aim for moderate effects only... or wait for clear, frosty days (is this where you tell me that you live in south Florida? ).
