What is with the weather??

They call this latatude the Roaring 40's. I think it needs a name change. Maybe something like the Guessing 40's or the Unpredicatable 40's. The name Roaring, only tells half the story here in Tassie. Just over two weeks ago we experienced 100km winds with 33 degree temps. This resulted in the most amazing site. Glowing bush fires lighting up the Eastern shore. The relentless winds spread the fires quickly. With three days of this craziness, the rains finally came, temps dropped back to normal and the fires were exausted.

Then....the snow came. The headlines in the paper read, "Tassie Defies Global Warming". It is getting colder as we go into spring. Strange plac.

The Southern Ocean effects can be felt at any time during the year as the Ocean circles Antarctica and crashes on to land in Southern Australia/Tasmania, New Zealand, South Africa and South America.

The Southern Ocean circles the earth and connects the Indian, Pacific and Atlantic Ocean basins.

I don’t think your rather extreme windy conditions are as a consequence of climatic warming, but it may give cause for increased frequency and intensity.

What your are experiencing is the remnants of winds from Antarctica.
Cold air from Antarctica interacts with warmer air from the ocean to form intense low pressure systems or polar cyclones that ride the Southern Ocean. The circumpolar westerly winds that blow unimpeded around the mid-latitudes are known as the "Roaring Forties".. These low pressure systems and polar cyclones bring unseasonable icy winds, storms and snow to southern Australia.

Best wishes

Those flowers must be so confused. I hope the weather straightens out for you soon so you can enjoy spring.

Take care,

Well...I think Lindsay sums it up! We have just had one of driest and warmest Octobers ever. The fall colors have never been so beautiful. Looking pretty wet heading into the first week of November though.

I wish we could say we've had a bit of dry weather. And sunshine, what's that??? Gloomy, wet, gray...that's what we've had forever...at least that's what it feels like. Oh well, this too shall pass. And then we'll have snow!
I must think more pleasant thoughts.
That's some weird weather you've had there lately. I hope your spring starts acting more like spring. Pretty flowers :)
