What are the years covered by the LDS

1987 and 2015

What is the typical climate of Beijing

Hot, humid, wet summers

What are the important notes of Jacksonville’s climate

What are the important notes of Perth’s climate

It is in the southern hemisphere so the seasons are the other way around.

What UK locations are near the coast

Cambourne, Hurn, and Leuchars

List all the variables recorded for UK locations

Cloud cover

What should be done to daily total rainfall values listed as ‘tr’

Taken as 0 or 0.025
