Skew-T log P diagram, 1000-400 mb (low level). This is a chart that is useful for working with inversions and performing accurate analysis of LCLs and parcels.

Skew-T log P diagram, formfeed version. This was presumably used for dot-matrix or teleprinter output from centers or from local software.
SOURCE: Unknown; probably U.S. Weather Bureau late 1960s.

Arowagram. This type of thermodynamic diagram was preferred by the U.S. Navy in the 1950s and was useful for calculating refraction.

Pastagram. The pastagram was introduced by John C. Bellamy in 1945. It is essentially a skew-T diagram but the upper part is an emagram.
SOURCE: Weathermasters Form JCB 460106 (1946), presumably for university or U.S. Weather Bureau use.
SOURCE (Literature): Bellamy, John C., 1945: The use of pressure altitude and altimeter corrections in meteorology. J. Meteor., 2, 1-79.
