Hey Dennis!

Still summer here, I guess this is the week. I'm a Shore guy too, though the missus dragged me over the bridge to Epsom. We move back over to Devonport next week though, so all is right with the world again. :-)

Where in the Bays are you? I was over at Fremont a while back decommissioning a satellite station - we pulled down antennas one by one and re-erected them here in Auckland.

Cheers!

Much is being made of global dimming temporary compensating the greenhouse effect. Measured Water evaporation rate (a standard test carried out for 100? Years) has dropped steadily and globally due to dimming over 50 years When we run out of dimming warming speeds up. Is this discussed anywhere?

And where did this hare-brained idea originate?

Careful, I've seen what might be 'bots' which post semi-intelligent replies to conversations. I'm not talking about the garbage spam that we all know like:

"3247n23.4.634&62##364 Red is wine flavor to color now? Debbie carat eats fried grease and dies. Do you know DVD? PC sale not today free purchase yeah! Tennis sports Debbie likes. Do you eat peas?"

Either that or maybe it's an AI that takes words from an existing thread and rearranges them into a new post that mimics the topic. In either case, it's either a person with poor english skills, or a really intelligent AI.

I'm hoping it's the former, rather than latter.

Visit news:alt.religion.wicca sometime - there's pretty much a consensus that "Lady Chatterly" is a bot.

: : I recently visited Auckland (New Zealand). Its now supposed to be : summer over there. I've had rain, hail, clouds and sunshine in one : day. According to a taxi driver its not uncommon to have all four : seasons in one day.

This is a saying that sometimes applies:- However, we have been having an extraordinarily wintery summer this year. The best summer weather is usually found in late January and February, despite midsummer's theoretical December date ...

We live in hope that that applies this year! We've been grateful for a forecast high that has lasted a good week or so, just now; it's made a change from the seemingly endless uncertain Spring through Summer!

But forecasters suggest that the remainder of the summer will be cool. ...

"Weak El Niño conditions are very likely to continue for the next three months, with below average sea temperatures around New Zealand in January tending average by March. Stronger than normal west to south westerly winds are likely for the three month period."

The local paper online weather news sections may give some impression.

Hail is actually typically a phenomenon of spring and summer! Hail traditionally falls from thunderstorms, but also from cumulonimbus clouds that are a bit short of thunderstorms, but generally requiring the cloud base to be above freezing (usually associated with air temperature at ground level substantially above freezing).

The frozen raindrops that fall from nimbostratus clouds in some winter storms is not hail, but sleet.

Larger hailstones (20 mm in dianmeter or larger) is one of two factors that can qualify the responsible storm cell as a severe thunderstorm. Most or at least a large number of storm cells that qualify on this basis are "supercells", which in the areas they form the most do so mostly from

2 months before to about a month after the summer solstice. Areas where supercells are most severe have some trend of getting them earlier in the "season", as in springtime. (The other factor that cn qualify a thunderstorm as "severe" is wind gusts 58 MPH-plus. A thunderstorm qualifies as severe if only one of these two factors is present. Rainfall and lightning are not factors for qualifying a thunderstorm as "severe" in the USA. A cumulonimbus storm cell having minimal lightning and dumping .1 inch of rain where it dumps the most rain qualifies in the USA as a severe thunderstorm if peak wind gusts at ground level or treetop level hit 58 MPH or more or if the storm cell drops hail reaching the ground with a size of 20 mm or larger.)

In most parts of the world that get a summer warm/hot season, temperatures on a long term trend maximize close to 3 weeks after the summer solstice - anywhere from 2.5 to 4 weeks, even 5-6 weeks where air temperature is greatly affected by an upwind body of water. The main exception is monsoon areas where spring is dry and summer is rainy - temperatures there may have a long term trend of peaking out closer to or even in some monsoon areas a bit ahead of the summer solstice.
