Meteorology B

thanks! and by the way what are feedback systems?

Does anyone have an idea of what to have on your cheat sheet?

I recommend having the full Koppen Classification on your cheat sheet. Almost every meteorology test I've taken this year has had Koppen on it.

thanks! and by the way what are feedback systems?

Here's how I've described them:

Because Earth's climate system is very complex and interconnected, disturbances in one variable will cause a change in other variables, which in turn can have affects on other variables, and so on. This can occur in cycles called feedback loops, in which a disturbance in variable A will cause a change in variable B, which in turn will cause a change in variable A. These feedback loops can be classified as either positive or negative.

Positive feedback loops are self-supporting; a disturbance in variable A will produce more of variable B, which in turn will produce more of a disturbance in variable A, and so forth. There are several important positive feedback loops in climate change, such as water vapor feedback and sea ice-albedo feedback.

Negative feedback loops are self-regulating; a disturbance in variable A will produce more of variable B, which in turn will reduce the original disturbance in variable A.

Example: the water vapor feedback loop: If the atmosphere is warmed, the air will have a higher water vapor capacity and generally the air will have a water vapor content. Because water vapor is a greenhouse gas, it will trap infrared radiation emitted by the Earth, warming the atmosphere further, and restarting the cycle.

I wish I was doing Meteorology again. Climate was the only one I didn't do :/
Everyday Weather was probably my favorite.

Well, good luck everyone

What are Semi-Permanent pressure cells and WHAT IS INSOLATION

What are Semi-Permanent pressure cells and WHAT IS INSOLATION

Insolation - this is very important to know, seeing how it will come up in every topic of this event. Insolation is an abbreviation for incoming solar radiation (INcoming SOLar radiATION). As I said, it's very common in meteorology, sometimes common enough to the point where it is sometimes not defined enough.

Semi-permanent pressure cells - areas of low/high pressure patterns that vary in position and strength (sometimes disappearing altogether) depending on the time of the year. For example, the Aleutian Low covers much of the north Pacific Ocean in January. However, by the time July rolls around, it has been replaced by the Hawaiian High as the prevailing pressure pattern in the north Pacific. Semi-permanent pressure cells are important to local climates because they describe the most common pressure systems that are expected to occur in an area at a point in time, which can indicate the most likely weather patterns (e.g., if an area is under a semi-permanent cell of high pressure in the winter, you would expect the area to usually experience conditions associated with high pressure systems more than those associated with low pressure systems).

Under the letter D, it includes the effects of longitude on climate. How does that work? I mean, it seems like it has no effect.

Latitude has a great effect on the weather as it determines how much light hits the areas (a lot at the equator and a little at the poles.

A feedback system is a cycle that repeatedly occurs, constantly changing specific factors which affect the cycle.

1st at Regionals!
Have you guys had any competitions recently? How did they go?

1st at Regionals!
Have you guys had any competitions recently? How did they go?

I've been to five invitationals this year. For Meteorology, I got 3 1sts, 1 2nd, and 1 3rd. Our regionals hasn't happened yet.
