I don't know, the DP rarely goes below 16c/60F here in the summer, most of this summer it has been moderately humid to very muggy (24c / 75F) but we barely had any rain though. It's almost never dry overall.
I grew up in a climate with lower RH but with more frequent rain / tstorms in the summer, so your equation does not work everywhere.
high RH + no rain ever = the worst. If it's humid it might as well rain. If it does not rain I prefer low RH.
Meh, it works for my climate. It seems in your region higher precipitation is caused by higher altitude instead of higher humidity which is the opposite here. I just despise hot and dry conditions where everything turns brown and looks dead in the middle of summer. I would take a FL summer any day over a Utah summer to give you an example. I love thunderstorms so I prefer a bit of humidity.
I don't really mind brown vegetation, I'm used to it, it is pretty normal in France when you have a long period of hot weather in the summer. I'm going there next week, I'll see if it's really brown ! And yet thunderstorms are really common there in the summer, especially near mountains or when a cold atlantic front comes to cool everything down.
Conversely, I was in Southern Italy recently (west coast) and everything was really green and lush. As I found out, we had dps in the high 70's / mid 20s.
It was unbearable most of the time. No A/C of course. It never rained though.
So when I visit a hot area and it's green... that's a bad signal for me ha ha.
I don't know. I hate scorching hot, dry days because there's usually no chance of precipitation which means fewer breaks in the heat. I'd rather have 90 F with a 75 F dew point and a 70% chance of storms, than a bone dry 100 F with a 40F dew point.
That 100°F and low humidity in Berlin was followed by intense severe thunderstorms from a cold front. Even the night before, there were overnight pop up thunderstorms that produced little rain but raised the dewpoint. Some cool cloud to cloud lightning.
So we had a nice Canadian High Pressure drop down which gave us incredible dry dew points and that same High pressure is now off shore and will give us 1 week of high humidity. Wish it didn't go off shore.
Too high threshold. 75-80 is atypical/too humid for deep tropical islands at sea level such as lowland Indonesia/Malaysia/Singapore... common dp is around 72-76/77 so more 70-75 than 75-80 range
