Following up on some thread topics over on CD Weather....
Has your local climate changed at all since the begining of the 20th Century....and if records don't go back that far, say post 1950 and then into the 21st Century ?
Warmer ? Colder ?
Wetter / Drier ?
POR greater than 30 years or better required for comparisons sake ( and no, don't wanna see backyard PWS data from Guilford, UK ....
)
Using the Southern Hemisphere example of Australia, it appears that post WW2 ( say 1950 ), mean annual temps have risen generally by approx 0.5c.
Interested to know what ( if any ) changes there are in other parts of the world.
A poll is included, 2 votes to indicate temps and rainfall means
My nearest local BoM official site is at Darwin Airport with records dating back to 1941
1941-1970 mean annual temp = 27.4c. Rainfall = 1578.3mm
1961-1990 mean annual temp = 27.1c. Rainfall = 1705.1mm
1991-2020 mean annual temp = 27.8c. Rainfall = 1832.4mm
The interesting feature of the changes is that min temps have only increased by 0.3c wheras max temps have increased by 0.6c since the 1941-1970 normals. And much wetter; over 250mm per annum more rainfall.
Also, our dry season months of June-Sept have warmed ( max temps ) by 0.7c-0.9c since 1941-1970. And even more shithously, the 'build up' months are warmer than 'back in the day', giving credance to the older residents saying that the 'build ups' are getting worse....
