Barotropic and Baroclinic Atmospheres

The video discusses synoptic scale features, focusing on barotropic and baroclinic atmospheres. Barotropic atmospheres have no temperature gradient, leading to no thermal wind or weather system development. Baroclinic atmospheres have intersecting pressure and temperature surfaces, allowing for weather system development. The video also introduces equivalent barotropic atmospheres, a type of baroclinic atmosphere with parallel temperature and height contours.

What are the two general types of atmospheres discussed in the video?

• Wet and Dry

• Static and Dynamic

• Tropical and Polar

• Barotropic and Baroclinic

In a barotropic atmosphere, what is the relationship between pressure and temperature surfaces?

• They are perpendicular to each other

• They are parallel to each other

• They intersect at various angles

• They form a spiral pattern

What happens to weather systems in a barotropic atmosphere?

• They develop rapidly

• They propagate without developing

• They dissipate quickly

• They remain stationary

What is the significance of the 700 millibar chart in understanding barotropic atmospheres?

• It shows the presence of jet streams

• It indicates a constant temperature across the chart

• It highlights the temperature gradient

• It displays the intersection of pressure and temperature surfaces

Why were barotropic models significant in the development of early atmospheric computer models?

• They simplified the complex atmosphere for initial modeling

• They were the most accurate models available

• They could predict cyclogenesis accurately

• They were the only models that could simulate jet streams

What is a defining feature of baroclinic atmospheres?

• Constant pressure surfaces are parallel to constant temperature surfaces

• Constant pressure surfaces intersect constant temperature surfaces

• They do not support weather system development

• There is no temperature gradient

What is the main difference between barotropic and baroclinic atmospheres?

• Barotropic atmospheres support cyclogenesis, while baroclinic do not

• Baroclinic atmospheres have no pressure gradient, while barotropic do

• Baroclinic atmospheres have no thermal wind, while barotropic do

• Barotropic atmospheres have no temperature gradient, while baroclinic do

In an equivalent barotropic atmosphere, how do temperature lines relate to height contours?

• They are perpendicular to each other

• They intersect at right angles

• They are parallel to each other

• They form a zigzag pattern

Why is there no temperature advection in an equivalent barotropic atmosphere?

• Because of the presence of jet streaks

• Because pressure surfaces are constant

• Because there is no temperature gradient

• Because temperature lines are parallel to height contours

How do winds behave in an equivalent barotropic atmosphere?

• They form distinct jet streaks

• They are weaker and inconsistent

• They are stronger but move at the same speed

• They vary greatly in speed
