AFMAN15-129 21 JUNE 2004 45Level700 mb850 mb&925 mbMinimum Parameters- Height contours using a base value of 3,000 meters at 30-meter intervals- Closed Highs and Lows with center height values- Isotherms at 5C intervals- Moisture areas. Color fill areas with DPD 5C or relative humidity 70% or greater- Height contours using a base value of 1,500 meters (750 meters for 925 mb) at30-meter intervals (or as required by season and documented in AFP)- Closed Highs and Lows with center height values- Short-wave troughs and ridges- Fronts aloft- Isotherms at 5C intervals (highlight 0C isotherm)- Moisture areas. Color fill areas with DPD 5C or relative humidity 70% or greater- Low-level Jet- Streamlines and circulation centers may be used instead of height contours andheight centers in tropical regionsEXCEPTIONS: May omit analysis for regions within the AOR with surfaceelevations reaching into these mandatory levels3.3.2.2. OWSs may:3.3.2.2.1. Use a meteorological satellite analysis over data-sparse areas.3.3.2.2.2. Produce an analysis of other pressure levels or parameters on standard levels (i.e.height fall centers) based on seasonal weather patterns or customer requirements.3.3.2.2.3. Analyze two levels over tropical areas: low-level (925 or 850 mb) and upper-level(300 or 200 mb).3.3.3. Standard Analysis of Upper Air Soundings (SKEW-T/Log-P Diagrams).3.3.3.1. OWS graphical displays will include:3.3.3.1.1. Temperature and dew point vertical profiles.3.3.3.1.2. Wind directions and speeds at mandatory and significant reporting levels.3.3.3.1.3. Tropopause height.3.3.3.1.4. Additional derived parameters (at a minimum):3.3.3.1.4.1. Height of the freezing level.3.3.3.1.4.2. Height and speed of the maximum wind.3.3.3.1.4.3. Lifted Condensation Level (LCL).3.3.3.1.4.4. Lifted Index (LI).
