What's the point in giving scientific names to cloud formations (for example, "cumulus nimbus") when they are constantly changing shape?

By looking at the cloud formations meteorologists can predict wheather patterns. Having a name for the formations helps, it just wouldn't sound very authoritive if they said "Judging by that big billowy puffy looking one, and the long streaky one..."

Meteorology is a Science. Naming clouds helps Meteorologist communicate what they mean to each other.
I studied Meteorology in college it is very interesting.

Although clouds can look a bit different in shapes, the scientific names are important as the "main" shape of each cloud, their color, their height and their type of precipitations (when applicable)is important. Any meteorologist would say they do not only predict weather but also predict various type of storms and the level of danger that is related to it. For example, a nimbus is a cloud predicting serious storms that require safety measures. If ignored, some people could be stranded and injured during such storms.

any useful feat that keeps 27 weather men employed is pretty amazing, isn't it?

the names are for the type of cloud not shape

They are named for their "type" of cloud. More for what's in them but too for what they look like.

They are named because of the density of the cloud & the potential for rain that it creates. The names are Latin. The meteorologist would sound kind of ignorant if he said that the day will be partly cloud with the long, thin, stringy types of clouds.

What's the point in giving names to the days of the week? They're constantly changing.

different countries, different races have different names for everything. . . for us filipino, rice is "palay", "bugas", in japan that is "gohan"

same on clouds, they gave scientific names just to make a common name for everything...

Why did my parents name ME when they knew I would be constantly changing over the years? LOL! Change is the universal baseline.

True they can change but it is also true they can be indicative of weather pattens which is vital in making forecasts. The little bit I know about it, clouds are considered to be one of the biggest unknowns in their effect and their predictablity which is vital for not just short term forecasts but how and when they form in realtion to more global events, such as global warming or cooling. People who study such things need a common language to converse. +5

Shape is not the sole aspect of different formations.

That is exactly the reason

Because as each cloud formation manifests, a different set of circumstances are occuring in the atmosphere, eg; cumulous, becoming cumulonimbus as a storm starts to form and so on through the cycle of the storm, from developing storm, to
mature storm, to dissipating storm clouds.
