Your analogy with an army is excellent. as long as we understand that we have more particles, higher density in a cold air mass versus a warmer mass, we can reason out the general weather pattern with without having to memorize anything else. I feel compelled to send I thank you donation through RU-vid.
Thank you for making the video with nice images. I just noticed one thing that the precipitation of the warm front is normally in front of it (the boundary with cold air), not behind it.
Excellent video and very educational and informative as usual, I watch it more than one time and I study on it, because i am a visualize guy so I can tell now with no confusion which weather is which. you're always very good nick on these lessons but now my question is I seen an orange lines which I think this is the rough air and I remember that because I have to abort one of the flight because it was there and as I remember it's between two similar front like it was between 2 warm fronts any more information about this rough air from your side, thank you, Sameh Ali
Good question. The orange dashed line represents a trough. A trough is an elongated area of low pressure. A ridge on the other hand would be an elongated area of high pressure. If you were to see a 3-D topographical map of just pressure where low pressure has a low elevation and high pressure a high elevation then the trough would be like a really long valley between two hills or mountains. Low pressure systems are generally associated with poor weather for pilots because of the rising air (turbulence, cloud formation, etc.)
@@PartTimePilot I think that's why my flight instructor cancelled the flight the other day add the I also shared your video if you don't mind on a big group of student pilots on Facebook for the others to benefit add learn from this video thank you for all the efforts that you put to help us
How does the air drop in density as it cools down, because isn't cold air more dense so I'm a bit confused on how the density is decreasing when the air is cooling down. Thank you for the video!
@@PartTimePilot 03:53 air density decreases with increasing altitude, but a cooler air mass is more dense than warmer air mass. I think @parisvanrensburg7241 is referring to this.
Hi Nick, thanks for the video. What difference in weather could I expect from a warm front and from a temperature inversion? Also, in a temp inversion, what causes the warm air to not rise much higher feet to cool, instead of staying low toward the ground?
Warm fronts have similar weather as temperature inversions as there is often a cap of warm air over colder air in a warm front just like in an inversion (actually called a frontal inversion). The weather you get also depends on where you are in relation to the front. As to why the air in the "warm layer" of the inversion does not continue to rise... that is a tricky one and one not easily described. I like to think of it as a hot air balloon. Hot air balloons rise in air because well they are hotter and less dense than the more dense and cooler air around it. Or in other words they have buoyancy. In a temperature inversion there is simply a point due to the changing lapse rate caused by various factors (radiation in radiation inversions, moving fronts in frontal inversions, etc.) where the balloon simply loses its buoyancy and there is a stable condition where nothing rises above a certain point "lid" of the inversion. The real answer gets into different lapse rates and the competing forces of the air wanting to rise naturally and things like radiation or fronts. This article goes into it if you want to read more about it: www.weather.gov/source/zhu/ZHU_Training_Page/Miscellaneous/inversion/inversion.html#:~:text=If%20the%20CAP%20is%20too,when%20they%20reach%20the%20CAP. Also, remember that eventually the air does rise and dissipate and temperature inversions are not permanent but when the forces that cause them are more than that rising force, they stick around.
