Here is my first question:
In what layer(s) of the atmosphere does temperature inversion occur?

I think its the Troposphere. Correct me if I'm wrong.

What forms thunderstorms?

[arwynp]

Nope, sorry. The answer is

Cirrostratus Clouds

Oh okay, I'll add that to my notes

List the effects of El Nino.

Hello! Since there are 2 questions...

El Nino effects (Click to Show Hidden Text)

El Nino warms up the Pacific Ocean (don't know how much sadly) and decreases wind shear in the Pacific. Thus, the western border of North America faces many more tropical storms like tornadoes and huge increases in precipitation.

What forms thunderstorms (Click to Show Hidden Text)

Generally speaking, thunderstorms are caused by rising of a lot of warm air and like how convection works, this warm air "rubs" with the cold air to create not only charged particles with electrons charging towards the ground (positively charged) but forms clouds that meteorologist call Cumulonimbus clouds.

Please help and explain to me the corrections if I got the questions wrong. This is my 1st time posting and I wish you all best of luck!

I guess I'll resurrect this thread.

1. At what point (ppm) will the amount of CO2 in the atmosphere be so high that the level is irreversible?

2. Explain how uneven heating by the Sun creates wind, and describe how the Coriolis force impacts wind systems.

1. This is just a guess but 1000 ppm? 2. Differences in atmospheric pressure create wind. Warm equatorial air rises higher into the atmosphere and migrates toward the poles(low pressure system) At the same time, cooler, denser air moves over Earth’s surface toward the Equator to replace the heated air(high-pressure system) Winds generally blow from high-pressure areas to low-pressure areas. The Coriolis Effect deflects wind to the right of it's intended path in the Northern Hemisphere and to the left in the Southern Hemisphere.

What causes frontogenesis and what is the difference between frontogenesis and frontolysis?

[LiteralRhinoceros]

Number 2 is right, but number 1 was 450 ppm (dangerously close to our current levels) Frontogenesis occurs when the temperature gradient changes (magnitude or orientation) due to changes in speed and direction in the wind field.
Frontogenesis is an increase in the thermal gradient, while frontolysis is a decrease in the thermal gradient.

Oh I didn't know that, thanks. You're correct but you didn't ask a question back.

1. How does one draw an isotherm, given the temperatures? (where are the numbers in relation to the line?)
2. What is a blue norther?

1. Isotherms are drawn in ten-degree intervals. Temperatures lower than the isotherm value are always on one side of the isotherm and higher temperatures are on the other side, while you connect the points that are the same. If the highest/lowest temperature value on the map equals an isotherm value, you're not supposed to draw that isotherm. If a temperature value appears out of place, you have to circle that value.  2. A Blue Norther is a fast-moving cold front that causes temperatures to drop dramatically. Common characteristics are a dark blue-black sky, strong winds, and temperatures than can drop 20-30 degrees Fahrenheit in a few minutes.
