Tropospheric ducting is very cool, under the right conditions it can create incredible dx.
Here is some good info about ducting and how it works.

Well worth the read.
I used to run 14 elements on 2 meters and had a lot of fun on that band.

Tropospheric ducting - just one part of tropospheric propagation
Tropospheric ducting is a type of radio propagation which allows transmission of VHF frequencies and above beyond traditional line of sight.

Ever take advantage of the Pineapple Express as they call it? Tropo ducting between Hawaii and southern California allowing 2m FM between them. That's a NICE 2500 mile opening when it happens.
I never worked the islands on 2 meters, but during the " dog days of summer" we used to work FM simplex from the south valley up to a group in Yreka CA.
Tropo is cool.

A bit off topic as it relates to radio https://oceanservice.noaa.gov/facts/pineapple-express.html you'll know I refrain from straying, the term "Pineapple Express", in my area of expertise, came back to mind. Again I'm caught in my undawares.

I keep trying to convince them but they are convinced FM there's no DX with FM and "lordy, where's my swing?"
I understand. But more often than not, we'll get someone a few thousand miles away listening to us talk, and will join in the conversation. The first time it happened I couldn’t believe it! On FM??? But yeah, with the right conditions, it's definitely possible. And locally, I'd have a hard time going back to AM.
We had decent group in CT on 2m FM horizontal and everyone ran at least 7elm. Some guys ran stacked 2m9's. From central CT i could rag chew with a guy in Long island with 65watts with ease.Tropospheric ducting is very cool, under the right conditions it can create incredible dx.

When tropo would pop in all sorts of crazy stuff would happen. One time we where talking to a guy in philly like he was local. NJ would pop in and out too.
Tropo is weird because when it moves it moves like a light switch. S9 then poof ,just gone.
