They did it again...

Unread post by NZ Thunderstorm Soc »

TV3 again had the current temperature for Dunedin in excess to what was the maximun high for the city.
Do they realize what what they are doing... or don't people take notice of what that weather-boy is saying ??????
I'm not going to whatch any more TV weather forecasts again and take there word for it.
I bet Kawerau is 31C today on TV One but the red highlight for the country's maximum will probably show Alexandra at 29C :x

Remember that the max temps are to 3pm when shown on the map of N.Z

And the current temps of the main centres are reading at 6ish.

Alexandra on a fine summers day tends to get it's Max temp later in the day however I dont think in Dunedin city the 6pm temp would be higher than the 3pm unless a warm N/NW wind blew in. I suspect they are giving the temp from the Airport at 6pm which can be a lot warmer than the 3pm city temp especially in a NE flow.

I think you'll find that for some places, esp. main cities, they are quoting the highest value for that place's main sites - since it is all some kind of silly contest - as if temperatures are the only criteria of weather "quality".

I don't think that's true. the Media reads the max temps from Auckland Airport, instead of Whenuapai, where it does usually get hotter.

Wellington's come from the Airport i believe (not Kelburn) as well as Hamilton's and Christchurch's

John, the temps they give out for Kawerau are accurate. It's the North Island's Alexandra ;)

I don't know where Auckland's readings come from, don't think it is the airport.

Wellington City Council had a new temperature reading site specially installed for TV broadcasting, its not out at the airport. They felt the old site was not representative of Wellington's mediterranean climate.

And the Dunedin figures often come from the airport. The airport readings are consistently inaccurate. The sensor there must now be sitting over the bitumen tarmac. The readings get too high on sunny days.

If you want an objective idea of temp. variation in NZ urban areas, you won't find it from the TV1 numbers. They do not quote any daily lows. So if they just quote daytime for Dunedin Airport, which has hotter days and colder nights than the Musselburgh town site, they give a misleading idea right off the bat.

If W'gton values were quoted both day and night for the Kelburn site that would be reasonably fair as it is quite a good representative. Nelson probably gets slightly maligned because the sea breeze cools the airport a little - again, no night temps.

But none of the TV1/3 nonsense should deflect anyone who is serious about understanding NZ climates. The various local bodies are so lacking in objectivity and commonsense that they want to dupe others into thinking that their weather is "better" than it really is, and in their simple-minded world this simply means pumping up the temp. values.

There's a town in northern Queensland (name escapes me now - maybe Tully) which for decades had the highest average rainfall in Australia - it was discovered later that a local had been topping up the raingauge regularly to reduce the competition's chances - cretin!

Even when you get away from temps. comparisons can be odious - Nelson wants to keep its regained title as sunniest town (over Blenheim, the previous holder, even though the difference has always been small anyway) - but it's quite likely that Nelson now has a very favourable exposure for its readings, and Blenheim less so than formerly - both plcaes have had several site shifts.

Refer to my already posted reply, plus NZStorm's.

I can believe that Kawerau's numbers are fairly OK as this would agree with long term official means which give it and Te Teko the highest value for mean daily maximum for NZ stations (that's in the summer months, and for the year overall too I think) though parts of eastern Northland come pretty close.

The folks on the Kapiti Coast had pressure applied to get their readings improved - now their values in sheltering from NE/E flows are really silly-looking at times. Too bad they can't cook their sunshine readings.

I know what you mean. My thermometers and gauges all live within fan-aspirated Stevenson screens, and recorded an Annual high of 32.6° on the afternoon of January 27th. Not a record by any means, but the hottest so far this year after all the inclement weather. Yet the radio stations still claimed it was 37° or something in Omarama, based on a reading from the thermometer hanging by the front door of the Mobil gas station.

Up in Twizel, their thermometer sits near the focal point of a huge concrete heat collection device (the Twizel Shopping Mall). They reported a high of 40+°...I made myself unpopular with some there when I suggested that the reading wasn't entirely accurate. One guy even accused me of trying to "steal" the highest temperature reading from Twizel!

Others around these parts have been telling me that the observatory office sensors in Omarama are "broken", because their own thermometers, usually badly sited, and often fully-exposed to the sun at some point of the day, consistently read much higher. Some people go by the gauges in their cars.

Ask the average man how tall he is and he'll always add an extra inch or so. Ask them to estimate weather conditions and they always exaggerate. I have no time at all for TV Weather reporting, since they are inaccurate to a ridiculous degree but, as you said, others engaging in some kind of half-assed competition are no better.

When I was in Alex on Saturday numerous people told me the the high the day before was 39C. Pick your battles, I just smiled and said "sounds hot" :-#

..the point I'm trying to make is that they should SHOW the actual maximum up to broadcast time at 6pm
If Dundein is 25C at the time the put the weather forecast out, surely that should show in the temperatures on their nationwide map??
I assume the temperatures are from the Musselborough Pumping Station where Dunedin city temperatures are taken from or are they from some new site in the Otagon??
Christchurch temperature are usually quite even between the airport and the gardens except maybe in NW conditions.

I'm reminded of human longevity and a few other things...
To veer off the subject a little, I'm curious about the Twizel freezing fogs in winter (was sometimes in Alexandra during a fog event) - how far north and south of there do they extend? I know the readings at Tara Hills in Omarama region indicated they didn't usually get them. When driving into Alex. from the south my family noticed that the start point of a fog layer was always the same.

I've yet to experience a hoar frost in Omarama (although I've only been here permanently for less than two years...been visiting three times a year since '96 prior to that); I don't think they got one in Twizel last winter either, although they usually do, and Omarama usually doesn't, I've been told.

Heh, Phil, I think what you really meant by "pick your battles" was "don't mention the weather", or "nod your head and keep walking"! :-)

A buddy of mine works for BHP at Port Headland where it routinely gets into the 40s. He says that without A/C you can't do anything. The guy who told me it was 45° up the back of Lake Tekapo while he was working (according to the gauge in his 4x4) must be some kind of superman I reckon! :-D

I gave up on a work discussion with a colleague who was convinced that March "is" the warmest month of the year (never mind up to 150yrs of obs. at hundreds of sites that say Jan or Feb, etc. etc.), on the basis that he was able to get his roof painted - it so happened that last Feb. here and in lots of other places in SW of N Island was easily the wettest and stormiest on record, while March was dry and quite sunny...

I suppose that would be the same for Tekapo? Haven't ever been there in winter months.

Man, it's pretty warm here right now. 30.8°, 24% humidity. It feels hotter though.

One time last summer while driving the Toyota up Benmore with a heavy load on the trailer the in-car thermometer read 54°...30 minutes after I'd reached the summit plateau and parked it was down to the mid 20s. I suspect a big, hard-working motor could possibly have had some impact on the earlier reading...

I was camped at around 1,930m, at the summit of Mt. Ollivier, near Mt. Sefton, on Saturday night. It was so warm I had to get out of the sleeping bag. I was told later that the freezing level was somewhere around the 3,500m level.

There's been a marked reddish haze over the Mackenzie this past week or so, and a lot of fine reddish dust on the snow; it's been suggested as a result of bushfires in Australia. Interesting stuff.

ps to tv3 temps for Dunedin...the figs are given to the tv stations by 4:30pm by metservice...it takes time to prepare the show for transmission...as tv3 dont have a weather centre like tvnz the updates dont usually reach them. So if the temp keeps rising as is often the case at this time of the year the broadcast values can be lower at times...I suggest you look at tv1 instead!!!..

cheers Steve
