During the summer months, storm patterns and tracks shift farther northward. By mid-summer, the threat for severe storms weakens and shifts to the central and northern plains states and the upper Midwest.
The impact of the longer duration of daylight is to warm the atmosphere enough to cause the jet stream pattern northward. As you may recall from our IQ Weather lessons, the jet stream is a main ingredient for strong storm formation.
When the jet stream drifts farther north and weakens during the summer months, severe weather becomes less frequent.
As the end of summer approaches, and the overall atmosphere begins to cool, the jet stream will typically begin to drift back southward slowly. That sets up a second min-severe weather season in the autumn.
Summertime is also the early part of the hurricane season! As of today, we have had 5 named storms so far. The peak of hurricane season is in September, and hurricane season does not end until the last day of November. As you...
At IQ Weather, we like to teach you new and different ways to look at weather!
In our 24-lesson video- based course, we talk about clouds and how they are formed. Today I want to talk about visual clues you can use to tell whether or not the atmosphere is becoming more favorable for storm development…using the look of the sky!
If storms are in the forecast for a particular day, often the air has to become unstable before strong storms can form. When we say the air is unstable, we simply mean that the air is rising, which helps promote the formation of precipitation and storms.
If the air is stable, it means that there is little or no vertical motion.
The clouds that form in stable air are usually stratiform in nature…in other words…flat and fairly uniform. It is quite common to see a lot of stratocumulus clouds during the morning hours before a storms form. Stratocumulus clouds look like this:
As long as the air remains stable, the clouds will look that way....
On February 7, 2020, in the Tapovan-Reni area of Uttarakhand's Chamoli district in Nepal, campers witnessed a huge glacier break that triggered an avalanche.
IQ Weather is constantly looking for videos that gives homeschool students a sense of the power of nature. The avalanche starts at the top of the mountain, and as the snow plummets down the mountain valley, it morphs into a mass of snow and condensation that makes it difficult to tell whether or not it’s actually snow or just a cloud! Watch the video to its conclusion to find out!
This also illustrates what happens when a large object forces air to move in one direction. The result is similar to what happens in a wet microburst! IQ Weather covers microbursts in one of our online video classes. If you have a chance to take our homeschool course, you will understand more about how this sort of phenomena happens!
