When bad weather stops moving, the outlook can get dire for the areas in its path.
On a hot and humid day, the fan is your friend. But ice cream won’t make the difference you think it will.
Weather forecasting is complex and challenging. The process entails three steps: observation, analysis and communication.
The key ingredients for a storm to undergo bombogenesis are an unstable atmosphere, temperature differences and high-speed winds in the upper atmosphere.
It’s hard to get accurate measurements, but a nationwide network of more than 8,000 volunteers with rulers and specific standards reports after every storm.
Extreme heat over 50°C is likely to become more common, giving us yet another reason for Australia to act fast on climate change.
Preparing for being active in cold weather can help keep us safe and increase our enjoyment.
The winter solstice is past, but bundle up – January is when winter really arrives in many parts of the Northern Hemisphere.
Although insurance is important in natural disaster recovery, government and property owners also play an important role in protecting Canadians against the impact of catastrophic weather events.
Salty water seeps into our soils and groundwater through surface runoff and storm-water pipes. The long-term storage of salt in the environment impacts aquatic life, infrastructure and drinking water.
Extended periods of rain are most likely found in locations where mountains are near oceans.
Forecasters described it as a ‘historical weather day.’ An atmospheric scientist who was at the heart of the storms explains what happened.
After one La Niña, the Pacific sometimes retains cool water which enables a second La Niña to form.
Tornadoes in December aren’t unusual in the Gulf Coast and lower Mississippi Valley states, but the Dec. 10-11 outbreak was extreme and far-reaching.
Climatologists study data over a long time to understand weather patterns and what causes them. Biometeorologists explore the impact that the weather and climate have on people, plants and animals.
New climate simulations show that there will be more rain and less snow falling in the Arctic by the end of the century, particularly in the fall and winter.
The southern parts of Australia are expected to become increasingly dry due to climate change. Yet, we now find ourselves subject to another La Niña event. What’s going on?
An atmospheric river is a band of warm, moisture-laden air many hundreds of kilometres long and hundreds of kilometres wide. It can dump prodigious amounts of rain over a large area.
At this stage it’s hard to know for sure, as there are many differences between the states. But it’s likely that climate plays a role.
