Vaga de calor (4.º dia em Lisboa)
O pico da onda de calor foi atingido no dia 5 de Julho passado para a maioria das estações segundo notícia divulgada hoje no sítio do Instituto de Meteorologia. Em Lisboa a temperatura máxima neste dia foi de 40º C, tendo sido registado em muitas estações do interior do país máximas superiores a este valor (no Alentejo e Ribatejo, por exemplo).
Hoje, em resultado da presença de uma baixa pressão a norte de Marrocos, a circulação de ar sofreu um desvio que impede a vinda tão directa de ar quente e seco do Sara. Assim, as temperaturas máximas já baixaram um pouco, especialmente no litoral.

Em breve a nortada chegará, manifestando-se em regime generalizado no oeste continental português e, consequentemente, a vaga de calor extremo terá terminado. Balanço: 5 dias quentes dos quais 3 muito quentes.
Veremos, nos próximos dias, se o Anticiclone dos Açores se mantém robusto (e na sua posição normal) ou, se enfraquecerá, permitindo o fortalecimento do seu "primo" da Europa Setentrional e Central e, ao mesmo tempo, estragando o verão continental do oeste português (através da sensação de tempo de "ar condicionado em força máxima").

Vaga de calor (3.º dia em Lisboa)
39º C, foi a máxima ontem. Hoje está a máxima já é um pouco mais baixa, apesar da manhã ter estado muito quente em Lisboa.
O campo da pressão no Golfo da Biscaia já está em declínio e, em breve, o ar marítimo vai invadir toda a costa ocidental portuguesa trazendo temperaturas muito mais suaves (a máxima em Lisboa deverá cair 15º C, dos 39º C para uns suaves 25º ou 26º C). A nortada vai voltar a ser muito forte e muito "fria"já no próximo sábado, como faz antever o modelo do campo da pressão à superfície previsto para o próximo sábado:

Vaga de calor
Se contarmos bem este é, em 2010, o 3.º conjunto de dias quentes que afectam o litoral ocidental português. Começou no domingo passado e terminará na 4ª feira com a entrada em força do ar marítimo, muito mais fresco e húmido.
Se não fosse o Oceano Atlântico, o litoral ocidental português teria um Verão tão tórrido como é o do litoral da bacia mediterrânica. Normalmente, quando este tempo quente e seco chega, o ar fica invadido pelo cheiro da esteva e do "chão de xisto" denunciando a proveniência da massa de ar que nos invade.

Palavras sábias de Obama:
"For decades, we have known the days of cheap and easily accessible oil were numbered. For decades, we have talked and talked about the need to end America's century-long addiction to fossil fuels. And for decades, we have failed to act with the sense of urgency that this challenge requires. Time and again, the path forward has been blocked—not only by oil industry lobbyists, but also by a lack of political courage and candor."

Nightmare vision for Europe as EU chief warns 'democracy could disappear' in Greece, Spain and Portugal
By Jason Groves
Last updated at 8:24 AM on 15th June 2010
Democracy could ‘collapse’ in Greece, Spain and Portugal unless urgent action is taken to tackle the debt crisis, the head of the European Commission has warned.
In an extraordinary briefing to trade union chiefs last week, Commission President Jose Manuel Barroso set out an ‘apocalyptic’ vision in which crisis-hit countries in southern Europe could fall victim to military coups or popular uprisings as interest rates soar and public services collapse because their governments run out of money.
The stark warning came as it emerged that EU chiefs have begun work on an emergency bailout package for Spain which is likely to run into hundreds of billions of pounds.
Crisis point: Demonstrators protest cuts announced by the Government in Malaga last week in an echo of the Greek crisis

A £650 billion bailout for Greece has already been agreed.
John Monks, former head of the TUC, said he had been ‘shocked’ by the severity of the warning from Mr Barroso, who is a former prime minister of Portugal.
Mr Monks, now head of the European TUC, said: ‘I had a discussion with Barroso last Friday about what can be done for Greece, Spain, Portugal and the rest and his message was blunt: “Look, if they do not carry out these austerity packages, these countries could virtually disappear in the way that we know them as democracies. They've got no choice, this is it.”
Other EU countries seeing public protests over austerity plans include Hungary, Italy and Romania, where public sector pay is to be slashed by 25 per cent.
Deputy Prime Minister Nick Clegg, who visited Madrid last week, said the situation in Spain should serve as a warning to Britain of the perils of failing to tackle the deficit quickly.
He said the collapse of confidence in Spain had seen interest rates soar, adding: ‘As the nation with the highest deficit in Europe in 2010, we simply cannot afford to let that happen to us too.’
Mr Barroso’s warning lays bare the concern at the highest level in Brussels that the economic crisis could lead to the collapse of not only the beleaguered euro, but the EU itself, along with a string of fragile democracies.
DICTATORSHIPS
GREECE: Georgios Papadopoulos was dictator from 1967 to 1974.
The Colonel led the military coup d'etat in 1967 against King Constantine II amid political instability. He was leader of the junta which ruled until 1974.
Papadopoulos was overthrown by Brigadier Dimitrios Ioannidis in 1973. Democracy was restored in 1975.
SPAIN: General Francisco Franco led Spain from 1936 until his death in 1975. At the end of the Spanish Civil War he dissolved the Spanish Parliament and established a right-wing authoritarian regime that lasted until 1978. After his death Spain gradually began its transition to democracy.
PORTUGAL: Antonio de Oliveira Salazar's regime and its secret police ruled the country from 1932 to 1968. He founded and led the Estado Novo, the authoriatan, right-wing government that controlled Portugal from 1932 to 1974. After Salazar's death in 1970, his regime persisted until it eventually fell after the Carnation Revolution.
But it risks infuriating governments in southern Europe which are already struggling to contain public anger as they drive through tax rises and spending cuts in a bid to avoid disaster.
Mr Monks yesterday warned that the new austerity measures themselves could take the continent ‘back to the 1930s’.
In an interview with the Brussels-based magazine EU Observer he said: ‘This is extremely dangerous.
'This is 1931, we're heading back to the 1930s, with the Great Depression and we ended up with militarist dictatorship.
‘I'm not saying we're there yet, but it's potentially very serious, not just economically, but politically as well.’
Mr Monks said union barons across Europe were planning a co-ordinated ‘day of action’ against the cuts on 29 September, involving national strikes and protests.
David Cameron will travel to Brussels on Thursday for his first summit of EU leaders since the election.
Leaders are expected to thrash out a rescue package for Spain’s teetering economy. Spain is expected to ask for an initial guarantee of at least £100 billion, although this figure could rise sharply if the crisis deepens.
News of the behind-the-scenes scramble in Brussels spells bad news for the British economy as many of our major banks have loaned Spain vast sums of money in recent years.
Germany’s authoritative Frankfurter Allgemeine Newspaper reported that Spain is poised to ask for multi-billion pound credits.
Mr Barroso and Jean-Claude Trichet of the European Central Bank are united on the need for a rescue plan.
The looming bankruptcy of Spain, one of the foremost economies in Europe, poses far more of a threat to European unity and the euro project than Greece.
Greece contributes 2.5 percent of GDP to Europe, Spain nearly 12 percent.
Yesterday’s report quoted German government sources saying: ‘We will lead discussions this week in Brussels concerning the crisis. It has intensified to the point that the states do not want to wait until the EU summit on Thursday in Brussels.”’
At the end of last month the credit rating agency Fitch downgraded Spain, triggering sharp falls on stock markets.
On Friday the administration in Madrid continued to insist no rescue package was necessary. But Greece said the same thing before it came close to disaster.
Yesterday the European Commission and the statistics authority Eurostat met to consider Spain‘s plight as many EU countries consider the austerity package proposed by the Madrid administration insufficient to deal with the country‘s problems.
