"relatively dry air" in the Caribbean? Not an expert in any way shape or form, but my guess would be that the air from over the water would be pretty humid. (Are you talking about fog over land, or over sea?)

@DanielGriscom I've read that the fog is thickest where there is a certain amount of arid air over the land which meets the very moist air over the sea. But my source could be completely wrong about that.

I'm afraid my sources are wildly varied and not especially reliable, ranging from various Wikipedia articles to a lengthy "suggestions for people moving to the tropics" article.

I have edited what is now factor #3 to reflect what appears to be misinformation or misunderstanding on my part.

@BarryCarter: I don't know. Would it? Would that make the question more answerable? As I say, I really don't understand much about meteorology.

# Estimating fog incidence based on ocean temperature

(Asked by: username_0 on 2016-03-08)

In the tropics, say the Caribbean, I have read that there is very often a lot of nighttime and morning fog. I have read that the crucial factors are

1. The ocean temperature
2. Cool nighttime air temperatures
3. The movement of air from areas above land to areas above the sea

Assuming this is more or less correct, I am wondering if there is any way to estimate the effect of a local rise in sea temperature, say by 1°C.

My guess is that you'll get more fog lasting later, but I don't really know what I'm talking about.

Note: if I have incorrectly described the issues at stake, I would be pleased to be corrected.
