MESONET TICKER ... MESONET TICKER ... MESONET TICKER ... MESONET TICKER ... September 9, 1999 September 9, 1999 September 9, 1999 September 9, 1999 A Very Non-Turbulent Ticker Today, the Ticker focuses on one of the most exciting facets of modern-day meteorology. That's right, it's time to talk about nighttime cooling! (cue brass band) Okay, okay ... maybe the topic isn't "sexy", as they say in the entertainment biz, but it's worth a look once in a while. Here's a map of three-hour temperature changes taken from 2:00 this morning: http://ticker.mesonet.org/archive/19990909/delta.tair03.gif And here two maps of the weather conditions during that period: http://ticker.mesonet.org/archive/19990909/first.wx.gif http://ticker.mesonet.org/archive/19990909/second.wx.gif The most significant cooling of the three hour period occurred in the area of the calmest winds during that period. Way back in weather school, they taught us that light surface winds meant low horizontal turbulence, which meant little mixing, which meant a tendency for more rapid nighttime cooling, especially with clear skies. And that's exactly what we saw last night. And if you can't get excited about that, what can you get excited about? ================================================== The OCS/Mesonet Ticker https://ticker.mesonet.org/ To subscribe or unsubscribe from the Ticker or for questions about the Ticker or its content Phone or Email the Ticker Manager at OCS Phone: 405-325-2253 Email: ticker@mesonet.org --------------------------------------------------- -C- Copyright 2023 Oklahoma Climatological Survey ===================================================
