This 3-hour workshop takes a closer look at & examines more in-depth the surface pressure charts generated by NOAA’s NWS, NHC, & the NWSFO HNL, first introduced in the Thursday April 19th, 2018 from 11:45 AM to 12:45 PM free seminar “An Introduction to Surface Pressure Concepts & Charts” as a prerequisite to this workshop.
- Conduct an exercise understanding true wind direction/speed wind barbs associated with low & high-pressure systems symbols.
- Discuss more in depth the surface pressure weather system’s symbols & their associated features (e.g., fronts, troughs, & ridges to name a few).
- Discussion & follow up exercise on being able to anticipate specific weather conditions (such as cloud types, precipitation, visibility restrictions, & winds), all associated with the common surface pressure chart symbols.
- Discussion & follow up exercise on the difference between “Issued” & “Valid” from the OPC’s analyses & forecast charts.
- There will be a discussion & follow up exercise on the 24 -hour interval specific depicted tracking & intensity trends (marine advisories & warnings) of the surface map’s L’s & H’s pressure centers.
- Finally, Lee Chesneau will presents his hierarchy for marine weather prediction, vessel routing & decision making.
