Rain is usually triggered by something which causes a drop in temperature of a moisture-laden air mass. However there are certain chemicals which can act as centres for the production of rain drops or ice crystals. If one of these chemicals, such as silver iodide, is introduced into a cloud, precipitation can be induced. This is called cloud seeding.

Where does a rainstorm occur?

A rainstorm typically occurs when warm, moist air rises and cools, leading to the condensation of water vapor into clouds. As the water droplets in the clouds grow heavier, they fall to the ground as rain. Rainstorms are often associated with cumulonimbus clouds and can happen in various regions around the world.


What is troposphere activity?

Troposphere activity refers to the various processes and phenomena that occur within the troposphere, which is the lowest layer of the Earth's atmosphere. This includes weather patterns such as rainfall, wind patterns, temperature variations, and the formation of clouds. Troposphere activity is responsible for the day-to-day changes in weather that we experience.


Where is the sun when a rain storm is happening?

The sun is still in the sky during a rainstorm. Rainstorms occur when the atmosphere conditions are right for precipitation, which does not necessarily block out the sun. You might not see the sun during a rainstorm if it is obscured by clouds, but it is still there.


Where do lightning bolts occur?

lightning bolts occur in the clouds.


What clouds do thunderstorms occur in?

Cumulonimbus


How do chemicals occur?

Elements are cooked up inside the hot interiors of stars, and spread to interstellar clouds by means of supernova explosions, and when those clouds condense to form planets, different elements encounter each other and then form chemical bonds because those bonds allow them to have more stable electron configurations. These combinations of elements are then called chemicals.


When do funnel clouds usually occur?

Funnel clouds most often occur in the spring and early summer and in the later afternoon and early evening.


What occur at frontal boundaries?

Clouds and precipitation


What causes snowfall?

A snowfall occurs when the clouds get really cold, and form ice crystals in the air. It can be as warm as 40 degrees Fahrenheit on the ground, yet be 0 degrees Fahrenheit in the clouds, which therefore would cause snow to occur


Why don't all clouds cause rain?

Not all clouds cause rain because the conditions within them aren't always conducive to precipitation. For rain to occur, clouds must contain enough water droplets that coalesce and become heavy enough to fall. Additionally, some clouds, like cirrus clouds, are composed of ice crystals and are too high and thin to produce significant rainfall. Other factors, such as humidity and atmospheric stability, also play a role in whether clouds will lead to rain.


Does lightning go from earth to clouds or from clouds to earth?

Lightning typically travels from clouds to the ground, but it can also occur between clouds or within a cloud. This happens when electrical charges build up in the clouds and discharge towards the ground, creating a lightning strike.


What cloud is layered but puffy clouds that occur at middle and lower elevations?

Cumulus clouds are layered but puffy clouds that occur at middle and lower elevations. They are typically associated with fair weather, but can develop into larger storm clouds if conditions become more unstable.
