Hoe staat de straalstroom?
Straalstromen bevinden zich in de hoge troposfeer (zie atmosfeer), net onder de tropopauze (figuur 3). De hoogte van de straalstroomas bedraagt vaak 9 à 10 km, wat ongeveer overeenkomt met een luchtdruk van 300 tot 250 hPa.
Wat is een zware storm?

What are jet streams?
In the United States, people often refer to the jet stream, but actually, there are many jet streams located all over the globe. Jet streams are fast-flowing, narrow wind currents that occur in the atmosphere. Their paths typically have a meandering shape, and they have the power to push air masses around and affect weather patterns.
How do I use netweather’s new global jet stream forecast map?
Welcome to our new interactive global jet stream forecast map here on Netweather. Drag the map around to move it, the mouse wheel will zoom in and out (pinch to zoom on mobile and tablet). The maps update four times a day – and are an initial small feature using this new mapping technology – keep your eye out for further additions soon.
How does the Jet Stream affect weather on the surface?
As jet streams flow around the world, they can push weather systems on the surface along with them. When a jet stream is strong, weather on the surface will tend to change rapidly, since the stream is moving these weather patterns away quickly. When a jet stream is weak,…
What are the westerly jet streams?
The westerly flows are responsible for the western disturbances experienced in the north and north-western parts of the country. These are of two types, westerly jet streams move to the north of Himalayas in summer and easterly jet streams move to the peninsular India. The movement of a jet stream affects temperatures and precipitation.
