I know nothing about geology but am from a place where there are always sudden thunder storms out of no where and I sometimes pay attention to our observatory rader screen.
So what I see is that sometimes huge thick red/orange/yellow clouds coming from the sea and we will know the whole day will be rainy, but sometimes the rader shows 30 minutes ago there’s absolutely no cloud anywhere near my city but then suddenly a green cloud shows up over an area and within 15 minutes it becomes orange and red, meaning there’s thunder storm and huge rain in that area.
Why? Those clouds just come from no where and can form from nothing to suddenly huge thick red thunderstorm clouds in just 15-20 minutes?
Thanks!
Edit: just in case you guys dont know what I refer to as green/yellow/orange/red clouds… I’m referring to this:– [https://www.weather.gov.hk/en/wxinfo/radars/radar_range1.htm](https://www.weather.gov.hk/en/wxinfo/radars/radar_range1.htm)

When air is warm, it holds a lot more moisture than when it’s cold, and that moisture is invisible (it’s not clouds yet, just humidity). When warm air with a lot of moisture meets cold air, clouds form very quickly and you can get thunderstorms. Does the weather data source you use show warm and cold fronts? They usual look like red or blue lines with little triangles or circular showing which way the line is moving.
