What is an omega blockade?
Denehauw: “There is a higher pressure area, two kilometers higher than aan de ground, that changes little from places. Op de hoogtekaarten can ever know the Greek letter omega (Ω) in her, vandaar de naam. We would like to know: the air pressure is about 1,013 hectopascals. Al what higher is, most of the time it is cataloged as higher pressure, and what storage is than the pressure level.
“Bij an omega blockade zie je uitzonderlijk hoge druk. For the coming days, a pressure from 1,038 to 1,040 hectopascals for the field. Het duurt een tijd eer je teruggaat naar een druk van 1.013 von daaronder. Het is not that reads 20 hectopascal per day. The higher the pressure is, the longer the higher pressure area is. That zit daar nog minstens vijf, zes dagen.
“The high pressure area means that there will be a longer period of time for all interest to be increased. When that came in the winter, it was cloudy, maybe we were drowning. Wanneer je zon hogedrukgebied raises Tussen Maart in September krijg je wel mooi weer, met hogere temperatures.
How long is the omega blockade supposed to hang?
“At least a week, it can be longer. Soms blijft het twee tot zelfs three weken duren.”
How does that work?
“In high druk heb ever dalende move. That wil zeggen dat de druk stijgt, omdat the air compressed wordt. Vergelijk het met een fietspomp: as each band van je fiets oppompt, voelt je pomp nadien warm, omdat je de air compressed.”
Why is the blockage over?
“The real omega blockade is at this moment both in Poland and in Eastern Europe, because the air pressure is great. The blockade is followed by one thing: there is a problem with another air supply and you have a warmer weather.”
Do you lose those regions that are in the middle of aan the edge of the omega blockade?
“We must have the omega blockade in one direction pressure areas in Boven Ierland and the Atlantic Ocean. Vandaar dat we raise the southern air.
“Aangezien wij eerder aan der Rand zitten, het blijft here is less stable. That weekend was worded in terms of days, with 12 to 13 grades, but that is still the case for the day of the year. He also thinks it’s raining on the job, so it’s still going to be a problem. Next week there will be temperatures of 17-18 degrees, near misschien zelfs sea.”
Is he now overall in Europe?
“Nope. A high pressure area on a plek wordt compensated for a pressure area on the elders. It is even important in the atmosphere. Was the omega blockade zit, I’ll take that drug now. That will also be a real indication of the pressured areas that are in the west and east of the city, and will also be blocked. That is now happening in the Balkans and Turkije. There was only a little more sea between them and it was possible for two days to overflow by the days of rain. He is now snowy.
“Het is dus een mes dat aan twee kanten snijdt: als je zit in zo’n hogedrukgebied, is het plezant, maar als je daar volldig buitenzit en je zit wekenlang met nat weer, dan kan dat ook voor zorgen problems.”
How uitzonderlijk is there a blockade?
“We have vaker blockades. I know he’s going to be there, but he’s coming for a reason. As each de hele aarde bekijkt, he is altijd wel ergens a hogedrukgebied dat a week blijft hang. Think about the expected periods in the years from 2017 to 2020.”
