Meteorology B

[EastStroudsburg13]

Come on, at least he's asking for something specific and not vague like "What do we do for this event?"

I wouldn't think that much to that stuff, maybe their characteristics an under what conditions green flashes occur in. Also maybe the fact that the colors of sunsets can change in regard to the components of the atmosphere. I don't think there would normally be that much on those topics, however.

I'm solid with most of the meteorology stuff but I think I'm missing something with emissions/energy/etc. I've got the majority of Earth's energy budget in my notes, where incoming energy comes from, where outgoing goes, why it happens, etc. and the vocabulary to go along with it. I can't help but feel I'm missing something in this area of the test. What am I forgetting?

We (my partner and I) were looking over our Meteorology test from the tournament, and they marked a question that we know for 100% certainty we got right, so I wanted everyone's input.

46. Zulu time is the time if you were in what area?
A. Zurich, Switzerland
B. Greenwich, England
C. Washington, DC
D. Hong Kong

The answer is B, because Zulu time is based on the GMT timezone, or Greenwhich Mean Time.
On the answer key, they marked that C is the right answer. Any thoughts?
And on a slightly less relevant note, they misspelled Washington. They spelled it Wasthington, DC!

Thanks

EDIT: Another odd thing we found:
One of the questions was

The troposphere reaches to a height of about __ miles.

The right answer is 7 miles. Except that they marked the correct answer as 12 miles. The tropshere reaches 12 kilometers, not miles. This test almost doesn't seem fair!

I haven't gotten back the test from Hutto to see our right and wrong answers but for those 2 questions, my partner and I put the same answers. We probably got them wrong too but I totally agree with our answers.
I agree that the Zulu question is Greeenwich. Here's some proof!- http://wwp.greenwichmeantime.com/ says that "UK is on Greenwich Mean Time (GMT)"
As for the troposphere question, here's some more proof! http://www.asknumbers.com/MilesToKilome ... rsion.aspx If you look at 7 miles it says
11.265408 kilometers.
I agree that those questions aren't fair but hey, there's nothing we can do. robodude, at least we know that we aren't going crazy or anything and forgetting the simplest things!!

True, true. If this was regionals or states I would be complaining to someone who mattered to see if we could get this worked out, but theres no point for an Invitationals. Pick your battles, as they say, and there's no point in making enimies with Beckandorf over a mistake at an invitationals.

Just wanted to point out an interesting fact that I heard today. Apparently, today there was snow on the ground or in the air in all 50 states. You never know what they might put on a test....

[brobo]

Nope, only 49. There was SUPPOSED to be snow in all 50, but none fell in Hawaii. There's a mountain that usually has snow on it, but none fell last night.
Just saying.

Ok some more questions here.

Firstly, a clarification. I know that as temperature changes, dewpoint stays constant, correct? My question is why does the dewpoint stay constant? We know that dewpoint isn't dependent on temperature but why does it stay constant?

For example, if the temperature is 75 and the dewpoint is 50 and then the temperature cools to 70, then would the dewpoint also change with the temperature or would the dewpoint stay the same?

Is there a rate of change that differs between the dewpoint and temperature (If the dewpoint changes with the temperature) and if so, what is it?

I know this is a lot but I greatly appreciate the help!

[zyzzyva980]

Dew point depends on relative humidity, right? If the humidity is 100%, temp and dew point are the same, but if the humidity is less then the dew point is lower than the temperature. I'm about 70% sure. Anyone have a second opinion?

you are correct is saying that they are different variables dewpoint is the temperature at which water vapor in the air will condense as dew or frost (which i think you understand) humidity affects dewpoint

for your second question no the dewpoint will not change just due to a temperature drop

The rate of change is mainly due the adiabatic rate of change as a parcel of air changes temperature due to rising or falling the dew point will change at 2C/km rising or fallling
