Weather school: Rare and unusual clouds

Weather school: Rare and unusual clouds

Canada’s Northwest Passage is currently open, albeit with some patchy ice

In this article we will continue our study of clouds by looking at several additional terms that can be used to describe and help identify them, and we’ll also look at some rare or unusual cloud types. Before diving into this topic, I want to do a quick update on the state of Arctic sea

Weather school: High, low, and middle clouds

Weather school: High, low, and middle clouds

Precipitation rarely falls out of stratus clouds, other than occasional drizzle

I know, I know — some of the long-range winter forecasts are starting to come out, so it must be time for me to take a look ahead to see what this fall and winter might have in store for us. Unfortunately, my review of all the different long-range forecasts is going to have to


Weather school: How are clouds formed?

COLLISIONS Clouds appear when atmospheric moisture condenses as droplets big enough to be visible

Last week we talked about how clouds are classified, then I said we would continue our look at clouds by examining each of the different cloud types in a little more detail, discussing just what type of weather we could normally expect with each type of cloud. We are still going to do that, but

Cloud types.

Weather school: It’s all about the clouds

TYPING Our current naming system classifies clouds by their height, then by their looks

Clouds, where would we be without clouds? Besides being esthetically pleasing to look at (if you’re not looking at them all the time), without them there would be no rain or snow, thunder or lightning, or rainbows! I know we have discussed the topic of clouds in the past, but I can’t seem to find

Telus buys Farm At Hand

Vancouver farm management software development firm Farm At Hand has become an arm of one of the Big Five in Canada’s communication services sector. Farm At Hand, which makes the cloud-based Crop Planner software suite for farmers and the Farm At Hand Agronomy suite for agronomists, announced Tuesday it has been wholly acquired by Telus

Cirrus clouds are those high wispy clouds that often look like they have been stretched or blown out into long streamers — what are often referred to as “mares’ tails.”

What’s the name of that cloud high up in the sky?

A quick look at how various types of clouds are named and classified

Our current method of naming and classifying clouds was developed in 1803 by Luke Howard, an English naturalist. His system employed Latin words to describe the clouds as they appear from the ground. Clouds that appeared to look like sheets were called stratus, which is Latin for layer. Puffy clouds were called cumulus, which is


Cold clouds will usually have a combination of ice crystals and super-cooled water, the first step in the process of creating precipitation in cold clouds.

Why cold clouds are the main source of summer rains

Even in the heat of summer the unique processes of cold clouds are important

If you missed my last article, we looked at how precipitation forms in warm clouds, after all it is the middle of summer. With the warm summer temperatures one might assume that most of our precipitation would come from warm clouds at this time of year, but in reality, most of our summertime precipitation comes

To turn into a raindrop, our little droplet would have to make a lot of collisions, as a typical raindrop is about one million times larger than a typical cloud droplet.

Most clouds don’t produce rain

The typical raindrop has to travel for about five to 20 minutes to reach your field

Originally, I was going to discuss the drought that has been impacting central and eastern parts of Manitoba, but thanks to some significant rains over the last week, the drought conditions, at least for the short term, have been alleviated. The rainfall did get me thinking about precipitation in general, so I dug back to


The atmosphere has a large number of particles for water to condense onto... but very few particles onto which water can freeze.

A look at different types of precipitation

Cold clouds dominate Prairie weather for most of the year — Part 1 of a series

With the mixed bag of precipitation that can typically occur during the spring across the Prairies, I thought it might be time to go back and visit the topic of precipitation and just how precipitation forms. Using a simplistic view, there are two types of clouds: cold and warm. A warm cloud is any cloud

A look at snow and super-cooled water

The water in our atmosphere has to be colder than 0 C before it’s cold enough to freeze

As we slowly work our way toward winter and several locations across the Prairies have seen snow, I thought it might be time to revisit the icy topic of snow. Instead of jumping straight into our discussion we’ll look at the process that creates precipitation in cold clouds, which, in our part of the world,
