They are a valuable aid in forecasting any weather conditions for any locality. and dissemination of radiosonde observations are discussed in other chapters of this train- ing manual. A constant pressure chart is a chart show- ing meteorological data at a particular stand- ard level. The meteorological data for these charts are obtained from radiosonde and ra- winsonde observations. The standard pressure levels mentioned are those levels for which mandatory data are transmitted in the radio- sonde code. These include the 1,000-, 850-, 700-, 500-, 400-, 300-, 250-, 200-, 150-, 100-, 70-, 50-, 30-, 20-, 10-, 7-, 6-, 3-, 2-, and 1-mb levels.

The constant pressure charts are designed to show these differences of pressure in space and time. Although constant pressure charts may be prepared for any or all of the mandatory levels, the most common charts in use are the 350-, 700-, 500-, 300-, 200-, and 100-mb charts. 210
