  2. includes: isobars (joins places of equal pressure), high and low pressure areas, air masses and fronts shows actual conditions at a specific time the pressure pattern is representative of the atmosphere up to 3000 feet issued 4 times daily at 6 hour intervals. Surface Weather Charts

  3. EXAMPLE 3

  4. Surface Weather Charts This is another example of a surface weather chart. Candidates are not required to decipher the chart. This information will be taught during the course next summer

  5. Upper Level Charts • show actual wind flow patterns and temperature aloft at various altitudes at a specific time • measured twice a day at 0000 Zulu and 1200 Zulu.

  6. Prognostic Surface Charts • is a graphic forecast • shows expected surface weather at a specific time in the future • issued 48 hours before they are valid and a second revised chart is issued 12 hours later (36 hours before they are valid).

  7. Upper Level Prognostic Chart (PROG) • a graphic forecast of winds and temperatures aloft for a specific time • prepared for specific high level altitudes • issued 4 times daily 12 hours before valid

  8. Significant Weather Prognostic Chart • shows forecast significant weather considered to be of concern to aircraft operations. • issued 4 times daily 12 hours before they are valid

  9. Confirmation Stage NOTE: You must use the buttons in the Confirmation Stage
