Establishing a 10 year climatology of 100.6 mm (4 inch) rainfall days, part 1

10-year period (1991-2000)

Then

Three additional steps to gain insight into possible reasons for the seasonal and geographic fluctuations of 100 mm days

Frequency of 100 mm (4 inch) events normalized to Louisiana in Winter (Dec-Feb)

Normals for mid-winter

Frequency of 100 mm (4 inch) events normalized to Louisiana in Spring (Mar-May)

Normals for mid-spring

Frequency of 100 mm (4 inch) events normalized to Louisiana in Summer (June-Aug)

Normals for mid-summer

Frequency of 100 mm (4 inch) events normalized to Louisiana in Winter (Sep-Nov)

Normals for mid-fall

A high percentage of the summer and fall 100 mm days are associated with tropical storms or hurricanes or their remains

Conclusions and what is next?
