I think you will find this very interesting to your question, notice that they havent updated for 2005 yet though...: http://www.aoml.noaa.gov/hrd/tcfaq/E11.htmlcalamity wrote:NYCHurr06 wrote:calamity wrote:Hmm… might be a dumb question (lol), but what was the most normal season on record for the Atlantic basin?
Hm...I don't know if you would be able to get a direct answer on that cause the definition of a "normal season" has changed as the seasons have gone on...i.e. what was normal in 1956 might be different now.
But, I am very interested as to see what others have to say.
That's true. Data and averages, etc., have changed since we’ve progressed through time, and it will be interesting to see what the others have to say.

Clockwise, Counterclockwise (page 3 I think).
The fact that storms in the northern hemisphere spin counterclockwise and storms in the southern hemisphere spin clockwise is because of the way we view them. When we view from the northern hemisphere ( n pole looking south) they spin counterclockwise. In the southern hemisphere is just the opposite we look from the southern hemisphere looking north. In reality if you were to view the northern hemisphere through the earth to the southern hemisphere both would be tuning CC and of course the reverse is true.

i had a theroy on that but wasnt sure

Put your finger on a globe and turn it... the pull is faster at the equator. In the northern hemisphere, the faster moving equator drags the bottom of the storm faster, so it spins counter-clockwise. In the southern hemisphere the opposite is true. It's just physics. Like on those merry-go-rounds as a kid, you could go to the middle and not fly off, but go to the edge and have someone give it a good push and you'd be in the dirt...

In theroy, twice a day. This is the case for the mid-latitudes. The lower latitudes (near the equator) will see twice a day coverage, if at all, because of the width of the Earth at this latitude. The higher latitudes (near the poles) will see more than twice a day coverage because of the frequent satellite crossing over the small point. (The higher the latitude... 24 scans a day is possible)
That's just the life of a polar-orbiting satellite.
(BTW, it scans all over the globe, where possible... not just over interest areas.)

I have a question... I've often heard of shear and shear maps and shear tendencies but what exactly is it? Is it winds aloft? or water currents? I'm unsure as to what exactly it is... Thanks...

This shows a fairly easy explination of windshear.

Shear is essentially a change in winds, whether it's a change in direction (directional shear) or a change in speed (speed shear). Shear can be figured as horizontal shear (a change in winds over the same altitude whether it's at the surface or aloft) and vertical shear (a change in winds over the same location, but at different altitudes).
The shear maps show how much of a change exists and the tendencies show what the trends are.
For overland thunderstorms, shear tends to help the system by adding a vent. However, tropical cyclones don't want this. The lower the shear (or the more uniform the atmosphere is), the better.

Follow-up Question:
As I have understood it, T numbers are used when there is an absence of recon. TD 4 has a Dvorak indicating tropical storm strength yet I don't see Debby getting a name. Without recon to the contrary, what is the reasoning for this?
