I understand that the "K" in ICAO identifiers indicate "US" but what does the"T" mean

[Andrew Clope]

I'm reading Tim Vazques' book Weather analysis and forecasting and I see where he says that for ICAO identifiers the "K" denotes US generally, "C" Canada, and "EG" Europe, but when searching around I see a few different ones, beginning in "T"

Are there two identifiers for the US?

T's are going to be the Caribbean islands.

Mike,

I'm confused then because on GR3 in the Chicagoland region, there's KLOT, TORD and TMDW?

I believe you are referring to the terminal Doppler radar sites. At least that is what the T stands for in TORD and the TMDW. I believe these have only been available on programs such as GR3 and Radarscope in the last year or so.

Yes, those are TDWR sites that are deployed near large airports. They're high-resolution radars that have a shorter range (among other differences).

Hawaii and Alaska start with "P". Some small protectorates and foreign military bases have other region letters as well.

I thought TDWR when I read this post last night too Shawn. Here is a layman's explanation of what they are used for (wind shear). Page 138 in your textbook, in the Appendix, lists the letters Mike referred to in his answer last night AD.

I'm sorry, I didn't consider the TDWR's, only the ICAO "T" identifier. Looks like everything should be cleared up now.

Thanks guys for the info!
