Page 13 - Jet Stream Pattern News Today

Thats what powered some of those enormous storms and the extreme weather that resulted. here in the uk, the same jet stream pattern is building this area of high pressure. weve had plenty of sunshine across most of parts of the uk today. the best of it arguably across the north and the west. we have had a bit of thicker cloud for east anglia and southeast england but that will continue to very gradually filter its way further southwards as we go on through the night. at the same time a little bi...

Time and i think that we do better in space if we collaborate more and i see that is what is happening now. lovely to talk to you. thanks for being with us. hello, again. a full uk forecast in a moment but first lets cast an eye on whats been going on in europe and that severe weather. here a picture from wednesday which shows a line of severe thunderstorms just locked in the same area for hour upon hour upon hour. we think the heaviest rain was towards the southwest of bonn where 158 mm of rain...

Seen across europe. this was as the storm really started pouring down. you can see the heaviest rain was across parts of west germany. the heaviest falls, actually, to the south—west of bonn, but also luxembourg in the firing line, eastern parts of belgium, the netherlands and into north—eastern areas of france. but it was to the south—west of bonn where we saw the largest rainfall totals with about 158mm of rain. now, we think thats around about three times as much rain as wed normally se...

A fine spell of summer weather just around the corner. the reason it is changing to become much more settled is down to this area of warm air pushing northwards across the atlantic. it has been changing the jet stream pattern. these waves have been getting much bigger. that will build an area of high pressure, but across in europe they get stuck with some low pressure which will bring some nasty storms into western areas of germany and some flash flooding over the next few days. but for us press...

We are going to find out on the other side of the atlantic much more undulation in the jet stream pattern, that will then propagate the jet stream and drive it to the north of the uk, which allows high pressure to build up from the south—west, from the azores, and settling things down. not just yet, though. sunday, weve got some more rain in the forecast. a fairly cloudy start, it will brighten up, well get some sunshine, that will then induce a few more heavy showers across northern england, ...

Affecting anyone. now, kit send cold air in different directions. think of a traffic cop. it does not affect the surface, though. just to give you an example, this shows you the colors of where all the cold is right now, typical, siberia through the north pole, canada and down here to the u.s., it is not under even the polar vortex. what happens -- this is the surface. >> in other words, this is just bad reporting that we are saying polar vortex all the time. >> it is horrible because so many pe...

Coast-to-coast, impacting tens of millions of people. whats the science behind all of the extreme weather? >> in terms of the storms weve seen in october, november, december, as i often tell peo e people, you know, the atmosphere doesnt have an on-off switch that knows when winter begins. >> dr. marshall shepherd is a president of the meteorological society. he said theres one big reason for the wild weather, the jet team. >> when we have the el nino-neutral conditions, the jet stream patterns, ...

The most. >> got plenty of salt. the back roads are starting to stick a little bit. it looks like its coming down pretty good right now. >> im going to stay in. >> because? >> stay out of the way. >> reporter: the winter storms have impacted tens of millions of people. whats the science behind all the extreme weather? >> in terms of the storms that weve seen in october, november, and december as i often tell people, you know, the atmosphere doesnt have an on/off switch that knows when winter act...

>> reporter: hes the president of the meet logical society. he says theres one reason for the wild weather, the jet stream. >> the jet stream patterns, we get strong dips in the jet stream patterns. in the dips, there could be cold air. in the hills, warm air. so, generally, the jet stream pattern is the governing forcing function of our weather in the wintertime. >> reporter: case and point, denver, colorado. in ten days they went from negative temperatures to a balmy 70 degrees. a time of year...

Ocean. and what this is doing, its having an effect. its melting ice. this is leading to higher sea levels, as well as the atmosphere is now holding more moisture. and that is leading, of course, to more rainfall, and then changes in the jet stream pattern. now, as we move over to our next graphic we want to talk about how this is affecting the day-to-day weather. and what were seeing the most evidence for. well, lets talk about heat waves. this time last year, we saw temperatures running about ...
