Yes, the elevation of mountains creates a climatic zone that helps stimulate cloud production and rain. However, this does not necessary mean it will rain because there are mountains. A drought can still affect the higher elevations.
Mountains tend to block rain clouds and produce more rain on the side of the mountain closest to the source of the rain clouds such as the ocean and make it dry on the other side. A good example is the coastal mountains of northmen California, Oregon and Washington. The Western side get a lot a rain and the eastern side is quite dry.
There is less rainfall on the lands beside the mountains. The mountains block rain. Also, clouds moving towards the lands rise to avoid the mountains, cooling the clouds even more. As cool clouds cannot carry as much water, the rain will start to fall on the mountains and not the land beside them. Thus, the lands beside the mountains hardly get rain and are dryer and hotter.
Mountains stop clouds and it rains there, mountains play very important role for rain to occur.
Here are a list of clouds that can make rain and/or snow:Altocumulus - can bring precipitationAltostratus - can bring rain or snowStratocumulus - can bring light rain or drizzleStratus - can bring minor precipitationNimbostratus - can bring constant precipitationCumulonimbus - can bring heavy rain, thunderstorms, or light showersContrary to popular belief, cumulus clouds do not make rain or snow. They can form together to make cumulonimbus clouds that can make rain or snow. Cumulus clouds can be a prediction of heavy weather to come if they appear at certain times of the day.Cumulus clouds are considered the 'fair weather' cloud, as they do not produce rain or snow on their own unless they form together into a cumulonimbus to do so.
There is no way for us to make clouds rain when we want them to. If we could do that then we would not be worried to much about it being to dry, we would just make it rain. Why can't seeding the clouds make them rain ?
rain clouds
When winds blow rain-bearing clouds towards mountains the clouds are forced to rise. As atmospheric pressure becomes lower the clouds are forced to drop their rain. This is why rain generally falls on the windward side of a mountain range. This precipitation is an essential part of the water cycle.
There is no known chemical that can make it rain. The closest is probably water vapor but people don't throw it into the clouds to make it rain.
orographic lifting
Yes it does as it is rain held in clouds before it reaches us.
The puddles from rain evaporates to the clouds and then falls as rain, snow, sleet or hail.. And it just continues.
The clouds can block sunlight and make it less hot/ dry and may be signs of rain soon to come.
