Hello how may I help you? Can you tell me what the biggest recorded cloud of all time was? Do you mean the biggest cloud as in the tallest cloud? Or are you referring to the heaviest? The heaviest cloud of all time please I did not really find anything for that. Maybe the widest cloud? Or the cloud that spanned the greatest length? Can you tell me what of clouds form the biggest storms? *what type of cloud forms the biggest storms Most often, cumulonimbus clouds are responsible for big storms. What is the lightest type of cloud? Cirrus clouds are usually very thin and wispy, if that is what you were looking for. yes. Thanks for all the info. You're welcome.
