UPDATE: I'm making materials available for all of my lectures on my website (melstrong.org) for either those bored folks stuck at home due to the virus or teachers looking for online content. For this lecture I have an activity looking at weather maps and identifying fronts.
In this lecture I go over how and why midlatitude cyclones form, and the behavior of cold and warm fronts.
This was originally part of the Blue Planet lecture series at the University of New Mexico. If you are interested in weather, this lecture is now part of my "weather short course" playlist, where there are another ~15 videos similar to this one.

As a pilot who flies a small plane near the Canada US border this was extremely helpful. This knowledge has improved my flight planning and improved my operating safety.

Our professor for Meteorology 1 explained us all of this through mathematical derivations, never showing us even a single illustration. Consequently I don't think anybody in my class really understood what the polar front and Rossby waves really are, even though you manage to explain it very clearly in 10 minutes using earth nullschool. I can't even tell you how helpful your videos are for me. I'm trying to hone my skills as a meteorologist, but it's very difficult to find people who understand the atmosphere AND who are good teachers at the same time, because our field is just that small.

Just Wow! This video answered all my doubts regarding mid latitude cyclones. This vid has so less views about this topic because it’s lengthier but people will watch so many other videos of short durations and end up wasting more than 1 hour with having more confusion and doubts. This video right here is gold. Thankyou so much Sir!

I really love watching your series. The structuring is pretty great and I think the examples, websites and your sketches contribute to your explanations well. That makes it really easy to follow you. Good job! I am excited what the rest of the episodes is all about and no matter what it is I hope you will continue teaching ^^ I honestly look at the clouds totally different now, knowing what they're telling me. So, keep up your good work!

Hi, I'm so enjoying your videos!! Thank you so much! Just a question or two. Does a hurricane ever form south of the equator and then cross the equator and go north spinning the opposite way?? Also, if there is sinking air in the center of the hurricane, why is that the center of the low pressure??

Hi Mel, brilliant videos for understanding the weather, nearly watched them all. Was wondering though if you could do a small video talking about what the winds do, ie backing and veering when you go through the fronts. I know winds 'veer' for warm front and 'Back' on the cold but could explain it visually how it works please.

Hi Prof. Strong, thanks for your lecture. I like your lecture. One question: Are polar front and polar jet stream same thing ?
@MelStrong
@MelStrong 2 жыл бұрын
Jet streams flow along the path where the temperature gradient is the greatest. So a polar jet follows the polar front. In reality, jets are discontinuous and split up according to the locations of air masses. But in general the location of the polar jet is along the polar front.

I would say the world map you show at the beginning, has the lattitudes of the parallels impropely displayed. 30º N parallel passes through Morocco and Texas actually. 60º N parallel should be below the arctic circle, which passes thorugh Alaska and Scandinavian peninsula. Besides that, thank you very much for posting
@MelStrong
@MelStrong 3 жыл бұрын
Yes this map looks to be made with a Winkel Tripel projection, where the latitude lines should be curved, not straight. But it is common with this projection that the latitude lines are drawn straight anyway, so you get a lot of distortion in different areas.

Has anyone ever calculated the perimeter, area, and even volume at each layer of the measured parts of the atmosphere for the polar front and vortex over time for a climatological graph? Yet another metric to track the changing climate. Average and median temperature for the large-scale air masses should be calculated as well as dew point averages as well. Counting and measuring the Rossby waves, their speeds, their frequencies and amplitudes over time, and reference every layer from the surface to the top. I feel like just measuring the area, intensity (temperature and dew points and pressures) as well as perimeter, waves and their features, then we would have a better grasp of the AO and AAO as well as the influences on climate and forcings in reverse. I just have never come across any area measurements of the polar front and polar air mass.
@Hexnilium
@Hexnilium Жыл бұрын
Heck, the ratio of the AO to the AAO would be an important feature. The differences over time would lead to an intensity differential over the entire earth like a voltage potential in electronics that would likely be yet another influence on the massively complex system of global climate. Like tracking each metric over time compared to their cyclical averages for AO area over AAO area, AO perimeter / AAO perimeter, AO mean temperature/dew point/pressure over AAO, AO Rossby wave count over AAO, and then calculating all this to see the anomalous conditions and look for yet more patterns. Maybe this is already performed as it seems rather logical, but I just haven’t seen the information.

I also have yet to see someone use AI to train on all this data to see if AI can generate better predictions further into the future in an attempt to minimize the chaos theory aspects of the unpredictability. Use AI in image prediction, but then much more detailed multivariate multidimensional (3 spatial, 1 temporal, temperature, dew point, pressure, winds, clouds, surface (ice, snow, land, water), and per each layer) version of AI neural network training and analysis.

I'd like to add on to it, could the Polar front also be known as the Polar jet stream?
@MelStrong
@MelStrong 3 жыл бұрын
The polar jet runs parallel to the polar front. Or in other words, the location of the polar front causes a strong band of wind along that boundary that we call the polar jet; as the polar front moves, the polar jet moves with it.
