Lightning Climatology: Most strikes in one day
I've been working on developing a climatology of lightning strikes in Alaska using the historical lightning data available on the Alaska Fire Service web site (23 years of data). Here is the plot of the most strikes in one day in the state, from June 15, 2005: just under 8900 strikes. Following long standing practice, a strike day runs from 6am to 6am, so this plots strikes from 6am ADT June 15th to 6am June 16th. It is ironic that on this, the max strike day of record, there are virtually no strikes over the Tanana-Yukon Uplands, the area of the state with highest climatological frequency of lightning.
