LAB #6 BRIEFING “Winds -1” – “Sky Condition” at GC and its relationship to Atmospheric Winds (in progress)
Essentially, we want to relate the current, observable appearance of (1) the sky condition (e.g., cloud types, lack or presence of pollution, etc.) and of (2) the direction and speed of surface winds to the isobar distribution, and thus to the Pressure Gradient Force (“PGF”), as seen on a current Wx Map! (As we do so, we also account for the effect of Earth Rotation upon wind-direction by way of the Coriolis “Force,” though this is only a secondary concern in this class. Nonetheless, this Briefing incudes a nice description of the Coriolis Effect.)
We will use the west side of Grossmont College as our “staging area” to view the sky, and aim our observations toward Cowles Mountain and Mission Trails Regional Park, and then northwestward beyond the Highway 52 above the greater “Linda Vista Mesa” (especially that portion upon which is built Miramar Marine Corps Air Station, and Mira Mesa, and the I-15, etc.).
For limited English or ARC students: I’ve submitted this for “closed-captioning” (though this semester, 3CMedia is way overloaded, thus I have no idea how long “cc” will take).
LAB #6 BRIEFING “Winds-2” – Wx MAP – 9/22/2020 @ 12Z (in progress)
This example of a Surface Weather Map is used to illustrate the information contained on the HANDOUT entitled “ATMOSPHERIC WINDS: Know the basics!” Much of the focus is on relating the winds and sky-condition on this day at Grossmont College to the regional pressure distribution as seen on the Wx map. Additionally, Time Zones are reviewed (especially in the context comparing San Diego’s time vs. 12:00 UTC (or 12:00 GMT, or “12 Zulu”)).

LAB #6 BRIEFING “Winds-3” – Wx MAP – 9/22/2020 @ 18Z and Pages 6 & 19 of Lab#6 (in progress)
This example of a Surface Weather Map (which is 6 hours later than in the previous video) is used to:
(1) Review and practice how to determine Wind Direction at various locations. Additionally, Time Zones are reviewed (especially in the context comparing San Diego’s time vs. 18:00 UTC (or 18:00 GMT, or “18 Zulu”));
(2) Complete the Observations (and “simple sketch” of the sky) plus the Predictions on “page 6;” and,
(3) Complete the Regional Pressure Distribution (at a CI = 2 [mb]) on “page 19.”
