J.S, Turkey is not in our area!We are Europe they are Asia despite the proximity
This is about climate, not about politics or any other thing. I understand the past, Portugal and Spain have a similar past of mainly wars. All over the world I might add. Has little to with our climatic region.
Anyway: I find the Meander valley and the station of Aydin most intruiging I have to say. Resembles Guadalquivir/Guadiana quite well!
Just looked up the data for Aydin for the decade. Well I be damned! Is that like a copy of Cordoba?
34,1/ 37,1/36,6/31,9...! Incredible, although I thought it would be slightly warmer. Station is at 57 m.
In terms of Amareleja I mean that it seems consistantly cooler to Cordoba and with big ups and downs.For example one day it can be 33 and the next over 40.In fact last week I was looking the IM site and the charts for Amareleja showed some significant ups and downs.Isnt that strange?
Well, that is a nice remark ! Actually made me find out a couple of things.
The dip is not confined to Amareleja, although it shows up there more clearly than some other stations but it is similar to Mertola, Castro Verde and indeed Sevilla and Badajoz show it. Finally Cordoba too, but less clearly.
Here are the values of Herdade dos Lameirões. Same height as Amareleja, 20 km straight to the south.
Herdade dos Lameiroes (agrometeo, measures to WMO standards btw):
0308: 39,9/27,5/13,9//rhmin 17,0//evo 5,3
0408: 39,6/29,9/19,2//rhmin 17,4//evo 5,9
0508: 39,0/29,2/16,9//rhmin 14,6//evo 6,1
0608: 40,3/29,3/15,9//rhmin 18,5//evo 5,9
0708: 40,9/30,7/19,5//rhmin 23,9//evo 6,5
0808: 34,2/28,5/22,5//rhmin 32,1//evo 3,2
0908: 40,5/29,5/19,8//rhmin 21,5//evo 5,0
The dip is clear, minimum relative humidity is higher, the minimum temperature is higher and evo is lower. All indications for less irradiation, in essence moist air=clouds/atalntic influence. The wind was 298 degrees BTW. So if it was constant Cordoba is expected to be warmer.
BTW: current august average in Herdade dos Lameiroes is 38,6 C (till 9-08). Yesterday it was 42,0-42,5 in the whole region. Amareleja, Mertola, Castro Verde and Portel Oriola...For Cordoba it is now 39,1 C. If I add 42,5 C from yesterday to Herdade dos L. it is 39,0 C. Like last month it is pretty close. Amareleja has been somewhat cooler the last days though....
Neverthelles: Corodba has only two days this month of 40+ (just), Portel has about 6 or 7 already, Herdade dos Lameiroes has been close to 40 C as you can see. The heat in Cordoba is more constant.
A peek at Sevilla..38,5 C. Badajoz 38,6, Moron de la Frontera 38,6..
Finally: the minimum temperatures. here we see huge differences between the two valleys, that are difficult to explain, but I guess the Portugese part is clearly drier.
Look at this:
Tmin in august thusfar:
Herdade dos Lameiroes: 17,4 C
Badajoz: 20,3
Cordoba: 22,3
Sevilla: 24,0 C
July average min temp:
Herdade dos L. 16.3 ( that is just 0.2 C warmer than Vlissingen KNMI!!!!!)
Badajoz: 18,6
Moron de la Frontera: 20,3
Cordoba: 20,5
Sevilla: 22,8
Two things: Sevilla is much warmer. Moron is in a similar location, but cooler at day and night. Portuguese inland stations are so much colder! Herdade dos Lameiroes is not the exception, but I'll stop adding data now.
It seems that the Guadiana valley (well, they are all a bit above the valley) is so much colder in summer at night. We have a big amplitude there!
Now regarding Athens.The observatory station is 7km away from the sea in the most prominent point of Athens historic centre ,the hill of Nymphs(well known in Ancient Greek history).It is the oldest station in the Balkan Peninsula with a recorded history of 180 years.
Now the unique phainomenon with Athens is that
it presents consistently a negative UHI during daytime due to multiple factors such as this extreme complexity of morphology(only Los Angeles resembles the Athens basin) ,proximity to the sea ,altitude and off course our famous Greek Meltemi winds!!
Here are a few papers
http://ieeexplore.ieee.org/Xplore/l...234401.pdf?arnumber=4234401&authDecision=-203
And here is the most well known publication for the Observatory station with an amazing analysis for the period 1860-1982! While the nighttime UHI is apparent almost everywhere in Athens the Observatory station and higher altitude areas are ''saved by the bell'' due to this amazing geopspatial position and off course due to other factors!
http://journals.ametsoc.org/doi/abs/10.1175/1520-0450(1985)024<1296:IOTUHI>2.0.CO;2
If you look at the tables for the Observatory of Athens station in the last pages you will be shocked to find out that Athens has exactly the same mean max from the 1860 period when Athens was only 50.000 inhabitants!
Thanks. I have to say that one day in october does not satisfy me at all. First of all: urban heat isles are much more prominent near the longest day.
Funny: inmy book about the Portugese climate they do exaclty the same. They show a infrared picture of Spain and Portugal on a day in the summer of and show the station data. The station data shows Cordoba to be warmer, the infrared is clearly warmer and larger in the Guadiana valley but it just does not cover a single station. Is this proof? Not to me.
In the summer and not in winter, spring or fall...But I'll read the study.
Are these data from Eleftherios Venizelos airport? If not, seems easier than deducing all kind of things form a city center.
I have to say that Athens is very interesting. Never thought of that, but it is!
