Stormy Weather II

[cloughie]

The Christmas Eve Harmony Choir’s sing through Falmouth this morning was marred by showers but that did not dampen the spirits of the 200 or so singers for this great real start to Christmas.

Not a cloud in the sky, and mild. Perfect!

Mild weather should see the remainder of the year out, and into 2020, starting from this Friday: high pressure to the SE bringing some warm air of Mediterranean origin, while fending off the march of the Atlantic lows, and keeping them well to the west or north-west.

A lovely cold, crisp and even Christmas Day today!

Touch wood, NO rain up here at all today c 5.44 p.m. - well, yet!!

...................and at 9.44, still no rain! Nasty easterly, but no rain.

Glorious day yesterday, horrid today. Rain just about all day. I had hoped to get out for a walk, but missed the brief window in the morning, so I'm hoping it will have cleared up somewhat by tomorrow when I have to go out whether the weather is suitable or not!

Very bad weather down south. High winds and pelting rain. Today looks a tad better!

[cloughie]

A flat, grey, nothing sort of day today.

About 28C yesterday (today for you; it's now nearly 7am on Friday) here in Melbourne, and sunny.

The furthest south and east I've been in my life!

Off to the beach (Ocean Grove) for a week today.
The horrors of 41C to look forward to on Monday, though.
:eek:
After that, it supposedly settles down to 24C (Wed), 27C (Th), and 32C (Fri).

S/A, can you advise whether Southern Hemisphere bush fires are likely to affect cloud patterns and other things over the near future? Not really asking about CO2, more visual and other results? Thanks.

I'm afraid my limited knowledge is of little use there. I'm not even sure how much the weather in the southern hemisphere affects that on our side of the Equator, if indeed it does. But I'll hazard a guess that the effects wouldn't be on the same scale as major volcanic eruptions have been, historically. I would assume that the knock-on effects globally (since I presume this is what you are asking) would be that tropical convection would become more and more restricted to the oceans, as plentiful moisture retention in trees is the main trigger when it comes to land-based rainfall seasonality. As concerning the availability of water and soil fertility, the resulting equatorward extension of the desert and savanna belts will most affect the peoples of those lands; hence population depletions and outward migrations. How quickly nature can adapt in our temperate regions will be critical either to maintaining the soil fertility necessary to feed all those extra hungry mouths, or growing technology adapted to laboratory conditions, which is a big ask at present-day levels of knowledge.

The aboriginals have long known about controlling vegetation fires by limited selective burning to create zones of sufficient width to limit the extent of naturally ignited fires and prevent leapfrogging. Native fauna are able to flee to safety. Here we create open zones, removing trees to prevent fire spreading. While I would think forests in tropical areas would be likely to re-generate more rapidly than in cooler parts of the world, the wholesale destruction of wildlife on the huge scales we are now seeing would deprive recovered areas of the mobile actors in their ecosystems, which depend on them for spreading seed, pollination etc.

Anyway, there are people on this forum far more qualified than me on this subject!

Thank you very much.

I guess satellites show how the smoke spreads? Is there a feed available from the space station? I will look for a website...

sciencenews.org has a fairly recent article on wildfires and how they can damage the ozone layer. A bit like a nuclear winter, apparently.

Not surprising.

Going to be rather dull.
