Why there is no rain when clouds are scattered?

AI Thread Summary
Rain occurs primarily from dense clouds, as scattered clouds often lead to evaporation before precipitation reaches the ground. While some rain may fall from scattered clouds, it typically evaporates due to insufficient density. On very cloudy days, the increased moisture content in the atmosphere enhances the likelihood of rain compared to moderately cloudy days. Additionally, weather patterns can allow for rain from isolated clouds, such as during pop-up thunderstorms. Overall, humidity levels and cloud density play crucial roles in precipitation dynamics.

Raining only occurs when there are dense clouds in the sky, when they are scattered the raining is stopped, why?

In many clouds, it actually is raining. It's just that there isn't much rain falling and it evaporates before it gets to the ground. In a larger, denser cloud, the rain reaches the ground before it has a chance to evaporate.
 
Rain comes from clouds. Clouds are opaque because they contain condensed water dropplets.
 
This is not always true. When I lived in Houston Texas, there could be a medium sized single dark cloud pouring rain as it crossed over you, with otherwise clear skies. As the cloud was approaching or leaving, you could see a "wall" of water coming down from the leading or trailing edge of the cloud.
 
Maybe I misunderstood the question. If he was asking why rain is more likely on very cloudy days than moderately cloudy days, it is because a very cloudy day has more moisture in the sky. On a moderately cloudy day, a cloud has an easier opportunity to dissipate instead of raining.

But as per the above, certain weather patterns can cause rain from lone clouds, particularly pop-up thunderstorms.

no, not necessarily ... you can have almost 100% humidity on a sunny summer day and not a cloud in sight. ie. the air/atmosphere is very moisture laden

its the concentration of moisture per unit of volume combined with temperature that will cause condensation and then precipitation

A cloud is at 100% RH (or greater), which is greater than "almost 100%.

Agreed.

Agreed.

just pointing out that you can have 100% humidity on a couldless day
