The weather will make

Test analysis:

Dense fog absorbs ground radiation and enhances atmospheric inverse radiation, which is the reason why the temperature will not be too low at night, and has nothing to do with visibility. A is wrong.

Dense fog reduced the loss of ground radiation, and B was wrong. Thick fog can reflect solar radiation and weaken it. Reduce visibility, right C. Dense fog can't change the wavelength of solar radiation, and D is wrong.
