Ranking hot weather

You are working on a global climate report and need to determine the hottest temperatures for various weather stations. Hawaii is next on your list to analyze and rank the hottest months on record.

Rank the HI weather station data by t_monthly_max. Rank 1 should appear first and have the highest temperature. Temperatures that are the same should have the same rank, but no ranking levels should be skipped.

You will need to join temperatures_monthly and temperature_stations.
