An observer left the following questions yesterday so I will try to answer them as best I can.
Q. How many Traces of rain = an inch of rain?
A. Subjective so no answer. What I call a trace of rain may differ from what you call. Neither are actually measured in the gauge. Meaning the first line on the gauge is 0.01 inches. There isn't a "trace" line.
If I am out doing yardwork and a shower or strom approaches but barely misses me, and I feel about a dozen drops of rain and actually see the drop mark left on the sidewalk -- I would definitely call it a trace.
You might want to see the entire sidewalk and other surfaces completely wet before calling it a trace. Or since it "traced" so much, but still didn't quite measure in the gauge, you might go ahead and call that big trace a 1 hundredth of rain.
Does that make any sense?
So since a trace is not really measured, but interpreted, who knows how many equal an inch.
Personally, if that question were on an exam I would answer zero, then give a verbal explanation like I did above.
Q. Concerning hurricane Ike, are hurricane hunter planes allowed by Cuba, to over fly their country?
I found online that NOAA is the only federal agency with hurricane tracking capabilities that is authorized by Cuba to fly in its airspace.
