Errata

For The Electrical Nature of Storms by MacGorman and Rust

Updated February 5, 2002

Default format is error => correction

Note: In ranges throughout the book, only the digits beginning with the most significant digit that changes are shown in the second number of a range (e.g., 235-237 is given as 235-7, and 476-486 is given as 476-86). This is Oxford's convention, not an error.

The following replaces the first sentence: Some scientists also have hypothesized that the mean peak current of ground flashes decreases with increasing flash rates. (Peak current does not appear to be well correlated with the charge neutralized by a flash, so this hypothesis is distinct from the hypothesis concerning neutralized charge.) However, such a relationship between mean peak current and flash rates is not generally true of ground flashes.
