9NZz-EeveJ8 0:00–1:19 — I'm actually Elizabeth's mom's cousin, and I work here at The Weather Channel.
9NZz-EeveJ8 1:25–2:44 — northward that's where the warm front is the cold front surging southward that's where we line up that cold front.
9NZz-EeveJ8 2:47–3:42 — your forecast is looking like as we go through the next couple of days. We're going to be looking at a little bit of rain.
UKHXfoKZxE4 0:01–1:05 — Today we're talking about fronts in aviation. To put it simply, a front is a boundary layer between two types of air masses.
UKHXfoKZxE4 1:08–2:16 — You may see some drizzle and then also the visibility is going to be poor, but is going to improve.
UKHXfoKZxE4 2:20–3:36 — In some cases, after the frontal passage, towering cumulus clouds will begin to dissipate and the precipitation are also going to decrease.
UKHXfoKZxE4 3:39–4:36 — To make things complicated, we actually have two different types of variants of occluded fronts.

字幕依据：I'm actually Elizabeth's mom's cousin, and I work here at The Weather Channel. I hear you guys are learning about weather, so we're going to talk a couple of things about weather systems and fronts and kind of how those all come together to make weather, and then we'll talk a little bit about your forecast. 9NZz-EeveJ8@0:00
字幕依据：northward that's where the warm front is the cold front surging southward that's where we line up that cold front. Then we zoom in closer, where we get all the precipitation. What's going to happen here is we've got this air coming down from the north and this air kind of going towards the north and east what happens is this piles up. 9NZz-EeveJ8@1:25
字幕依据：your forecast is looking like as we go through the next couple of days. We're going to be looking at a little bit of rain. We've got a couple of fronts to the south. Here's our warm front see the red with the half circles? 9NZz-EeveJ8@2:47
字幕依据：Today we're talking about fronts in aviation. To put it simply, a front is a boundary layer between two types of air masses. Now, for pilots, you need to be paying attention because any approaching front means that there is going to be a change in the weather. UKHXfoKZxE4@0:01
字幕依据：You may see some drizzle and then also the visibility is going to be poor, but is going to improve. If we have variable winds after the passage of the front, the visibility eventually is going to improve, but hazy condition may also exist for a short period of time. UKHXfoKZxE4@1:08
字幕依据：In some cases, after the frontal passage, towering cumulus clouds will begin to dissipate and the precipitation are also going to decrease. In some cases, where a fast moving cold front is present, we will see squall lines, squall lines are narrow bands of thunderstorms that form ahead of the cold front. UKHXfoKZxE4@2:20
字幕依据：To make things complicated, we actually have two different types of variants of occluded fronts. We have a cold front occlusion and we have a warm front occlusion. During a cold front occlusion, what we see is we have the cold front air mass that is colder than the warm front air mass. UKHXfoKZxE4@3:39
