1040 hPa anticyclone ?

[Lawrence]

Is that free or not? Miles of legalistic junk...

Yep,I know Just click accept at the bottom and away you go,it's totally free.

[RWood]

And then? "Place names" doesn't seem to yield towns (I want to see the topographic info around a given town)? Does one need to know their lat/long in advance?

[mikestormchaser]

Yeah 1037hpa here to, temp of around 6 or 7C average winter temperature

On the left hand side there should be a search Icon , when you click on it, it will ask for a place or road, insert the name and it will come up with a choice.

Should look like this:-

Search tool
Enter a place name or a road name to search for.
Then hit the search button to perform the query against the database.
Find a Place/ Road called: Amberley

should come up with:-

Rec Place name Location NZMG X NZMG Y Description
1 Amberley Hawke's Bay Region 2831980 6155740 HSTD: Homestead
2 Amberley Beach Lagoon Canterbury Region 2492590 5782030 LAKE: Body of inland water
3 Amberley Beach Canterbury Region 2492250 5781410 LOCALITY: Defined area of low or nil population
4 Camberley Hawke's Bay Region 2837180 6168510 SUBURB: Component part of a town
5 Amberley Canterbury Region 2488320 5783480 POPULATED PLACE: Populated area less than a town

yes, approaching my previous record high baro of 10.37.4 on the 8th sep 2004
nice web site and banner Gary McConnochie, well done

Thanks Brian. Managed to get to 1040 this morning, a record for me.

[Manukau heads obs]

baro started to drop here today with the incoming tasman low
(and the windy easterly wind with high cloud made for a cold feeling day (high of 12.8oC or so only here today)

Thanks! Couldn't read the icons very well but the help does actually describe them...

The recent 1040hPa anticyclone moved Ne over the Tasman Sea and weakoned as it moved over the top of the country.
The next one according to ECWMF looks set to form in the Australian Bight.

Anticyclones are not always sunshine, this is something I found on metservice's monthly feature page:

Ten reasons to hate a high (anticyclone):
Anticyclones are usually associated with light winds and sunny skies but they also have some undesirable attributes, especially when they get blocked and linger:

1. Near the centre are "dead" winds and usually an area of low cloud causing dull days called "anticyclonic gloom", or dirty air which may turn into fog.

2. Round the rim, winds are strong. If the central pressure is over 1030 “its going to get dirty” so look for a gale somewhere on the outside of a high.

3. Highs intensify the trade winds in the tropics. It may take about a week for a high to travel eastwards past New Zealand, and during this time the stronger trade winds tend to give night-time rain to the eastern side of the larger tropical Islands. In Fiji this is sometimes called BOGI WALU.

4. The bigger the highs are, the slower they move, blocking the fronts and lows that are trying to follow them. When this block is released, the western (“back”) end of a high may become a breeding ground for storms.

5. Intensifying highs tend to squash together the isobars between themselves and any nearby low pressure centres, creating “squash zones”.

6. A deepening low-pressure system and an intense or lingering anticyclone get together like the arms of an eggbeater and create a zone of enhanced wind and rain.

7. As air flows around a high, it spins out across the isobars and speeds up until it is as much as 20% MORE than that indicated by the isobar-spacing.

8. If a range of mountains blocks the air flowing around a high, the air tends to squeeze around the mountains rather than flow over them. This splits the wind flow over New Zealand into rivers of wind and puddles of calm. Sometimes a narrow gap is made just above the mountains through which pent-up air may be suddenly released at a rapid rate.

9. In winter and spring a high may bring unwelcome frost.

10. In summer and autumn a high may allow sea breezes to converge and, if it is cold enough aloft, this can form thunderstorms and hail.

Another wonderful blue dome day today up to 18C, great day to be on the Port hills for a walk.
Makes me wonder wether spring is already here or not even though its only 5 days out .
End of this week coming could bring the temperatures up in the east with some rather strong NW winds be interesting to watch for .
Cheers
Jason.

Looks like another 1040hPa anticyclone looming, to come in behind the current cold wintry outbreak, to cover NZ in the next few days

Yes I did see that, looking like highest pressures will be over the south island at this stage, should allow some hard frosts to develop down there

[NZ Thunderstorm Soc]

Up to 1044hPa at midday today in the Tasman Sea

[David]

Forecast to weaken to 1035-1040hPa while over NZ, highest pressures still look likely over south Island.
May give a longer run of settled weather and frosty mornings to the South island but a depression is forecast to move down onto the North island this sunday

[Andy]

Bar at 1037mb at the moment. Frosty tonight

[Michael]

If it clears 6° is a bit high

[David]

If it clears 6° is a bit high

It is.
I would say if it clears up this evening and the wind drops to calm it could go down to 3C, but depending on when the skies clear it could be more like 5C
