elevation at X?
2. Which side has
the steepest slope –

Air mass – is a large body of air
that has similar temperature,
humidity, and air pressure
throughout.
Cool

Cold front – a boundary

HW
1.Today, was there a clear boundary between
cold fronts and warm fronts? Other than the
symbol, how can you recognize that boundary?
2. Use the screenshot of wunderground. Today,
were there more high pressure systems, low
pressure systems or about the same? Explain
what the weather might have looked like today
across the U.S.
3. What data can we use to forecast tomorrow’s
cold and warm fronts?
4. Did the wind map help to explain any
weather patterns you saw on wunderground
(use the screenshots)? Explain.
