Precipitation and atmospheric temperature profiles

Meteorology 101: The precipitation we receive depends on the air it meets along the way

Precipitation is a vital aspect of Earth’s climate and plays a significant role in shaping our environment. From gentle drizzles to heavy snowfall, precipitation comes in various forms, each with unique characteristics and formation conditions. This week we’ll delve into different types of precipitation and the atmospheric conditions necessary for their creation. In the last

Cold-cloud precipitation and super-cooled water

Meteorology 101: Cold clouds dominate Prairie weather even in summer

Preliminary numbers for October’s global temperatures are coming out and they don’t look good. According to the Copernicus Climate Change Service, operated by the European Centre for Medium-Range Weather Forecasts, October 2023 was the warmest October on record globally, with an average surface air temperature of 15.3 C, which was 0.85 C above the 1991-2020


October ends up as average

Can we expect a relatively warm and dry end to 2023?

After a warm September across the Prairies, the first half of October continued in September’s footsteps. Above-average temperatures graced all three Prairie provinces for the first two to almost three weeks of the month. There was not much precipitation, making for absolutely beautiful fall weather. The wheels didn’t quite fall off, but winter made an

The planet continues to get hotter

Global air and ocean temperatures are at record levels

Let’s talk about record-breaking temperatures. Not daily records, not records for a city or country, but global temperature records. You may have seen an article or two about how September shattered the record for warmest month, after the warmest August on record. It looks like 2023 will be the hottest year on record for the planet. Let’s dig a


Let’s remember that warm, dry September

OUTLOOK | The various weather models lean toward near-average precipitation ahead

I know I say this nearly every month, but wow, did that last month go fast! Maybe it was all the nice warm weather we saw across much of Manitoba, Saskatchewan and even into Alberta. Before we do our monthly look back and then peer ahead to see what the last three months of the

Early-spring and late-fall frosts

The Winnipeg area may see a record-long frost-free stretch this year

It’s time to talk about fall frost and the length of this year’s frost-free season. So far, most areas of agricultural Manitoba have not yet experienced frost – or have they? Data for major centres shows a number of locations came close to frost on Sept. 12, and I found 10 to 15 locations did


El Niño and chaos theory

Will Western Canada have the textbook warm and dry El Niño winter?

El Niño can affect the kind of weather we might expect this winter. The formation and movement of one system can impact how other systems behave around the world. This is called teleconnection, which refers to the long-distance relationships or connections between climate events that occur in different parts of the world. This fundamental concept

Summer was mostly warmer, drier than average

The current El Niño may take us into a warm, dry autumn

Summer 2023 has come and gone, and weather-wise, it was a bit of a mixed bag across the Prairies. Large parts were dry, some regions wet, while a few lucky locations received the perfect amount of precipitation. Summer started off hot, then went cool over eastern regions before turning back to average by the end.


Extreme rainfall and a warming planet

Meteorology 101: A warming world may spur development of more blocking patterns

So far, none of my discussions about severe weather have manifested in an big outbreak of severe weather, so for those who are superstitious, we can put that to rest. In the last issue we discussed several factors that can result in extreme rainfall events. These ranged from simply having lots of atmospheric moisture to

The factors that contribute to heavy rainfall

Storms are a fact of summer life — but what makes a heavy rainstorm?

Last time we started our look at one of the last severe summer weather events, extreme rainfall. I looked back at the weather articles I have written over the last 20 years, and I only found one other article that talked about the causes for extreme rainfalls and that was back in 2015. So, I
