Abstract
This note discusses the theoretical aspects of the errors in measuring curvature due
to taking streamlines as trajectories
to taking isobars as streamlines
to combining these errors by taking isobars as trajectories.
It is shown that, in addition to a scale factor error associated with movement of the isobaric and streamline systems (this has already been noted by other writers), there are errors associated with
The difluence of the isobars and streamlines
The rate of distortion of the systems
The angle between isobar and wind.
By choosing the right place in the isobar and streamline fields some or all of these errors may be avoided. Otherwise any one of them may be significant.
