Re: Seguimento Europa 2010

Well I do not really care what you believe or what you like for that matter.I like the real extreme dynamic and this is neither in Portugal nor Andalusia.In Iberia only Murcia has what it takes for extremes having all the official records.It is by far the easiest place to reach 50.0C in Iberia!

Strange that you havent seen Athens being mentioned the last 3 years considering Athens has topped yet again the Portuguese national record with the amazing 47.5C in June 2007 in N.Filadelfeia!It seems that the boring 40-41's are of greater interest compared to the 48C Athens has managed in two areas on the same date and which btw Portugal has never reached officially!

O recorde oficial na Iberia é o da Amareleja (47,4 e 47,3 em ambas as 2 estações meteorológicas), Múrcia esteve perto com 47,2.

Everyone has his/her own taste. So no problem there. What I and anybody else thinks is important to you. It is your nr.1 goal it seems: to change our opinion. I have seen some forums where you tried to do so.
 
Re: Seguimento Europa 2010

Very nice evening here!! The showers came in, with a very nice shelf jsut developing before it came over my city. I filmed its development from a higher appartment in my city. Was greaat to see: the shelf and behind it the torrential rains!

Here are some pics from the other side of the ria of the shelf that by that time had just passed over my city. Pics are not mine of course.
A second one passed over us 2 hours later, but at 23 hours local time it was dark. I saw nothing. But the thunder and rain were nice yet again. And so we hit 230 mm this month. And there seems ot be some more to come.

Which two exactly are you talking about?

Murcia is measuring in an another enclosure btw. A meteorological garden of a very small size with a large building 30 m away or so. Yes, in that way you ensure high maxima....

Just because you did not know of Murcia and Athens extreme dynamic,it doesnt mean I change someone's mind or opinion.I believe I am being very informative for others.People can hide behind the frequency of 40-41C all they want to, still this does not change the fact that the areas in Amareleja and Andalusia are neither the warmest on average in Europe during the summer nor do they have the strongest dynamic in terms of extreme temps dynamic.Geomorphology plays a key role when dealing with extreme events.That is why you see Murcia,Catania and Athens being on the top of the list in the highest temps ever recorded in Europe.

São ambas ( as da Amareleja) do IM.
Pois, assim é complicado...
Talvez fosse melhor começarem a postar fotos das estações.
 
Re: Seguimento Europa 2010

Essa história do local com o valor mais alto está a ficar um pouco obsessiva e não me parece que seja assim tão importante para determinar se um local é mais quente o mais frio. Por exemplo, Agadir, em Marrocos, já deve ter registado mais dias com valores superiores a 45ºC que qualquer outro local na Europa, mas apresenta apenas 26,4ºC de média das máximas no mês mais quente (normal 1961-1990). Portanto, há na Europa muitos locais bastante mais quentes que Agadir, mas que nunca registaram, nem vão registar, valores de temperatura tão elevados como nessa localidade.

47,2 C in Murcia is warmer than 47,4 in Amareleja? If it is so special, how come it can't come higher than Amareleja? And Murcia measures in a Stevenson screen which selfheats easily in lowwind conditions. And Murcia is situated in similar conditions as Sevilla San Pablo, as I already told you.

Dear Sir,

with reference to your e-mail of March 25th 2010, we inform you that the extremes of maximum temperatures resulting from our official archive have been measured by the weather station of Bari Palese(ENAV) on July 2007,with 45.6°C, followed by Catania Sigonella(AM) with 45.4°C, registered on July 1998.These stations belong to our net, managed by Italian Air ForceMeteorological Service and ENAV (Civil Aviation), and follow the strict standards required by WMO (World Meteorological Organization) on measurement procedures.

P.S So for Italy we should consider 45.6 in Bari as the official temp record compliant with WMO guidelines and procedures that comes from the official Italian authorities"


Now how is Catania warmer than 45.6 in Bari? Or 46.6 C in Sevilla and Cordoba. 46,1 in Portel or Coruche? Or indeed 47,4 in Amareleja?
Why are you talking about Catania if you already knew they did never reach these values? Or do you dsicard high temperatures when they rival Elefsis, like Catenanuova but than use them when they suite you?

You wrote this message on a UK forum in april 2010....Forgot about that too?

Penso que se tem que abrir um tópico para esse assunto.
E seria interessante se aparecessem mais fotos de estações meteorológicas e da zona onde estão inseridas.
 
Re: Seguimento Europa 2010

Esta discussão da temperatura mais quente é offtopic, pode ser claramente discutidas noutro tópico, portanto foquem no que é "seguimento europeu".

Aqui pela Islândia sigo com temperaturas diurnas na ordem dos 15-20ºC, bastante quentes para a época, e 5-10ºC à noite (já negativas no interior do país). A noite aqui segue com 7ºC e céu encoberto.

De facto cansa um bocado o tipo de discussão «a minha pilinha é maior que a tua».

Well I also participated in the Italian forum since you were so eager to discredit me basing my arguments from Italy and the Italians report values higher than that so for Catania definitelly we need to make proper reasearch on it's values even though the 48.5C of Catenanuova is not official and the only official station they have in Catania is far from Catenanuova.

Also in terms of Murcia,well the record is 47.8C last century and indeed it has been officially accepted by AEMET even though it was last century.So there you go Amareleja drops to number 2 position officially in Iberia!


The point is that neither Andalusia nor areas in Portugal have any special dynamic compared to areas next to the sea as we have seen at least at an official level compared to the Athens basin and Murcia Plains.Athens systematically beat any area in Iberia in terms of absolute maximums.

The most important element is that regardless of what you like to notice or not,scientifically the warmest area of Europe is defined in terms of mean 24hour temperature...and as you can see there is no mach for Athens in Europe for this.I doubt that Amareleja can have a mean summer average higher compared to a normal Greek city.In this way I deconstruct the notion that inland areas are more prone to areas close to the sea when it comes to extremes temperatures...Thanks to your example from Antalya and mine from Athens it seems that Iberia with the exception of Murcia is really nothing of substansive importance in the warm climatology of Europe!Athens has seen 48.0C by the sea!Come on,who can really top this by the sea in Europe?I mean who?

Whether Athens is that very warm place or not, is not sure. There is evidence to at least have reserve and not to scream it out in a (to me) sensationalist style.

The reasons for reserve are:
- Peerreviewed research that shows a little effect on the average maxima and a strong effect on the minima by the city heatisle
- Unknown sensorscreen type, unknown surroundings
- You and I have shown that WMO is no guarantee whatsoever (De Bilt, San Pablo and many others).
- And as this is a intercomparison, we need to know equipment en sensortypes are used of both stations when we intercompare. Nothing is known about the greek stations

Your remarks about Murcia:
- If its orography is so special, why did it not reach the same temperature as Amareleja for more than 150 years now. If the orography gives way to superdynamics, is it gone? There is no proof of it
- I do have proof here however that it measures in a Stevensonscreen in a meteorological garden, which is a garden with a large building at about 30 m and a hedge of trees (low trees) at 20 m. Despite that, nothing above 46 C in the last 30 years. Amareleja and Cordoba went above that value various times.

Even if it has been is 0.4 C warmer than Amareleja in 189x and it is correct, is this what extreme dynamics do? Is that what gets you excited. Is it this 0.4 C difference between places that makes one much more capable of reaching 2 C more and the other not?

Then your attitude during discussions and why you discredit yourself. You use facts in two ways:
You mention them on one forum when they suite you and forget about them when they don't. Do you know what a nice description of reason is? It is that you use the same principle in similar discussions.
You don't, you use them when they suite you and that is unreasobale: You use double standards.
Examples are:
- A high maximum average is boring, but a high daytime average is in fact what your comparison is based on and what you seem to be excited about. These two things are in direct conflict with one another.
- You mention Catania as also easily "outperforming" the Guads regions when it comes to extreme maxima, while you in fact asked the Italian metoffice for a definitive answer and it was 45.6 in Bari, not Catania. You mention this in a discussion with some Italian guy, that was the official max according to you. That is lying by omission.
In this discussion you however use unoffical values to prove your point and start talking about Catania. If others use unoffical values, you do everything to discredit them. But it is okey for you to use them whenit suits you.
- You raise eyebrows about remarks of WMO stations measuring totally wrong, while you proved that point yourself already on another forum (San Pablo)and happily stated that this was a ridiculous way of measuring the climate. Which yu did before and during this issue became an argument over here.
Again it is easy to see that it suited you there, but it does not suit you in a discussion where WMO station in general are not accepted just like that but someone (like me) asks for more info about screentype, place in a field or near buildings etcetc....
- You say you don't care about what other think, yet your mission is to deconstruct myths. Myths are things in peoples minds, not buildings. The only thing you are trying is changing peoples minds. It is therefor of the utmost importance what do think, if you want to change a myth..

And this is all is easy to understand why: because it is your goal, as can be read on other forums as well, to get rid of the myth about the heath in the Guadalquivir region. Whenever you can, whenever you can use an argument that suits you, you use it. Catania debunked there, but used as proof here. Average is boring here, but remarkable in Athens etcetc.

Meteorologists and amateurs alike are impressed, for years by the constant daytime maximuma in the Andalusian Guadalquivir basin. I think you stand little chance of changing that. Certainly when I look at the outcome of the various discussions you had on various fora.
 
Re: Seguimento Europa 2010

Não, o AEMET não usa a referência dos 47,8ºc.
Só usa a referência dos 47,2ºc.
Acho que este assunto devia ser discutido noutro tópico.

Resumen de Extremos Climatológicos de España (actualizado al 31 de diciembre de 2007). AEMET:

"Ateniéndonos a los datos registrados a partir del año 1900, y teniendo en cuenta que tanto la instrumentación como las características de los emplazamientos de observación se estandarizaron durante las tres primeras décadas del siglo pasado, podemos decir que el valor más alto de temperatura es 47.2ºC, registrado en Murcia (Alfonso X) el 4 de julio de 1994"

"Sin embargo si se considera la totalidad de estaciones climatológicas donde se hacen o se han hecho observaciones de temperatura, el valor extremo de Murcia es superado en algunas de ellas, pero estos datos son muy dudosos."

Si además se incluyen en el estudio los datos registrados en el siglo XIX, aparecen valores de temperaturas por encima de los 47,2 ºC de Murcia . Pero también se duda de su validez pues se desconocen las condiciones en que se hacían las medidas.

Así encontramos datos como el registrado en Sevilla, Iglesia de la Anunciación, de 49.8 ºC medido el 11 de julio de 1873. Allí también se midieron 48.5 ºC el 15 de agosto de 1893 y 46.8 ºC el 19 de junio de 1897, e incluso hay referencias de una temperatura de 51.0 ºC el 30 de julio de 1876. Este dato no se halla registrado en la Base de Datos Climatológica pero sí se encuentra en el anuario de las observaciones meteorológicas de la Península de dicho año. Sin embargo parece que las medidas se hicieron en condiciones deficientes con instrumental instalado en la cúpula de la iglesia, donde había un termómetro en una garita tipo facistol y protección de tipo Montsuris, y no fue hasta 1912 cuando se instaló una garita estándar."
 
Re: Seguimento Europa 2010

Now a squalline passes from my city all the way to the NE over the country...and not without its effects of course.

Outra vez chuvas torrenciais aqui com 15 C e muito (muito!) vento. Ha tormbas sobre o mar, mas ca nada disso....Vamos atingor 300 mm de precipitação neste mes do agosto nalgumas regiões Holandesas. O clima torna-se mais e mais chuvoso no NW de Europa...

Edit: with the rain temperatures dropped to 13.1 C here and on the coast of Noord Holland (near Amesterdão) 11.7. That is pretty cold for this time of year.http://middelburg.zeelandweer.info/

As we can see: it is 12.3 C now (17.33) and the coldest palce in The NEtherlands is now at 11.3 (warmest about 16 C).

12.2 at 17:48 h.....12.1 C now (17.52). Despite a very warm Northsea. And I like it, don't get me wrong. This weather to me is 10 times better than sun, 30 C and 50% humidity. A just put on a sweather and I'll be fine. I have no airco hear, so no such luck with sticky 30 C Dutch weather.

Finalmente: os records entre 1971-2000 na minha Atlas Climatico do KNMI (maximas absolutas entre 0-24 h UTC).

Vlissingen 14.5, De Bilt 14.1, Twente 12.9 C. Hoje, o maxima fui entre 15 e 17 C em Holanda. Mas 11-12 C durante um dia em agosto e um pouco estranha....
