Hi guys, Ayshah here, with your last weekend update from the Newsround | :00:00. | :00:00. | |
team. On the way: It's been called BMXing | :00:00. | :00:09. | |
on snow - we'll tell you how Great Britain got on in the awesome | :00:10. | :00:12. | |
Snowboard Cross. And from snowboards to surfboards - we'll bring you the | :00:13. | :00:16. | |
curly tale of the pig who rides the waves. This is Newsround. | :00:17. | :00:27. | |
So, first - all this week we've been telling you about some truly | :00:28. | :00:29. | |
extraordinary weather conditions that have been causing terrible | :00:30. | :00:32. | |
problems, not just here, but in America, too. So what's causing all | :00:33. | :00:36. | |
this weird weather? As I've been finding out, it's all to do with a | :00:37. | :00:48. | |
global wind, high above us: the jet stream. | :00:49. | :00:54. | |
The UK has been lashed by waves and thrashed by winds and rain. Over in | :00:55. | :00:58. | |
the US, they are in the grip of a bitterly cold winter that shows no | :00:59. | :01:02. | |
signs of easing off. Some scientists don't think this prolonged bad | :01:03. | :01:06. | |
weather is just a coincidence. They believe the recent warming of the | :01:07. | :01:09. | |
Arctic has moved the weather system that drives conditions here in | :01:10. | :01:12. | |
Northern Europe, and over in North America. But this current here in | :01:13. | :01:24. | |
red - it's called the jet stream. This year, it dipped lower than | :01:25. | :01:28. | |
normal, making the weather stay the same for longer. It's caused months | :01:29. | :01:31. | |
of heavy rain and storms for us, and extreme cold for America. Scientist | :01:32. | :01:34. | |
Jennifer Francis has been studying the jet stream. She thinks we could | :01:35. | :01:38. | |
be seeing more of the same in the future. | :01:39. | :01:41. | |
I think we can expect more of the same. I think we should expect it to | :01:42. | :01:44. | |
occur more frequently. It being these wavy patterns in the jet | :01:45. | :01:47. | |
stream that tend to result in weather conditions being very | :01:48. | :01:50. | |
persistent in one place. It's too early to judge whether the | :01:51. | :01:54. | |
jet stream's change in shape will be permanent, but the research suggests | :01:55. | :01:57. | |
that we may have to get used to winter weather that stays the same | :01:58. | :02:03. | |
for weeks or even months. Back here in Britain, the Prime | :02:04. | :02:06. | |
Minister has warned that flooding misery is likely to continue for | :02:07. | :02:09. | |
millions of people, despite a break in the bad weather. David Cameron | :02:10. | :02:12. | |
said that many places in southern England, where the ground is already | :02:13. | :02:18. | |
soaked, may see further flooding. One of the biggest threats is not | :02:19. | :02:21. | |
from rivers bursting their banks, but from water underground, coming | :02:22. | :02:31. | |
to the surface. Check this out. One of the reasons we are seeing so | :02:32. | :02:35. | |
much flooding at the moment, in some parts of the country, is ground | :02:36. | :02:38. | |
water flooding. This happens when water rises from rocks under the | :02:39. | :02:41. | |
ground and comes out at the ground surface. When rain falls, some of it | :02:42. | :02:45. | |
soaks into the soil, and the rocks beneath the soil can also carry and | :02:46. | :02:49. | |
store water. When enough rain falls in these areas, water keeps moving | :02:50. | :02:52. | |
down beyond the soil layer into the rocks beneath. Ground water tends to | :02:53. | :02:56. | |
flow from the higher ground to the lower ground. When we have a lot of | :02:57. | :03:00. | |
rain, ground levels rise and the water starts to come out of the | :03:01. | :03:03. | |
ground surface in places that are usually dry. We call this ground | :03:04. | :03:06. | |
water flooding. It takes longer to go away than flooding rivers. Over | :03:07. | :03:09. | |
flooding tends to last days or weeks, where is ground water | :03:10. | :03:13. | |
flooding can last weeks or even months. | :03:14. | :03:22. | |
Next, we're off to Russia and the Sochi Winter Games. Today, we've | :03:23. | :03:25. | |
been enjoying a thrill-packed sport that's been likened to BMXing on | :03:26. | :03:31. | |
snow - it's the snowboard cross. Six riders carve down the course, | :03:32. | :03:34. | |
braving huge jumps and sharp corners, and with everyone so close | :03:35. | :03:37. | |
together you can have some nasty crashes. Team GB's Zoe Gillings | :03:38. | :03:40. | |
qualified for the semi-finals this morning - you're watching the end of | :03:41. | :03:44. | |
her semi here. Zoe came within just a few centimetres of making the | :03:45. | :03:47. | |
final, but unfortunately she just missed out. She was gutted to be so | :03:48. | :03:51. | |
close, but says she'll be back for more in four years' time! | :03:52. | :04:00. | |
I thought I'd actually got through at one point, because one of the | :04:01. | :04:03. | |
official guys said I'd got through, but then it turned out I wasn't. It | :04:04. | :04:08. | |
was a real shame to miss out on the final by that small amount, but I | :04:09. | :04:12. | |
rode as hard as I could and as fast as I could, so that's all I can | :04:13. | :04:16. | |
really do. I definitely want to do another Olympics, there's no | :04:17. | :04:19. | |
question. If I can get the funding, and the results keep coming, then I | :04:20. | :04:23. | |
don't see any reason why not. Well, you've been telling us about | :04:24. | :04:26. | |
your Sochi highlights over on the Newsround website. | :04:27. | :04:43. | |
Thanks so much for all those comments, keep them coming in. | :04:44. | :04:47. | |
Im curling, this morning, Britain's men's curling team were beaten 7-6 | :04:48. | :04:51. | |
in their second to last round robin match with Norway this morning, so | :04:52. | :04:54. | |
they're not guaranteed a semifinal place yet. The match went down to | :04:55. | :04:58. | |
the final end of the game with the scores level at 6-all, but the | :04:59. | :05:01. | |
Norwegians won with the final stone. Team GB can still make the semis if | :05:02. | :05:05. | |
they beat China tomorrow afternoon. Britain's women play their last two | :05:06. | :05:11. | |
matches tomorrow as well. In today's matches, Arsenal will be | :05:12. | :05:14. | |
hoping to avoid another scoreline like this when they face Liverpool | :05:15. | :05:18. | |
again in the big four o'clock showdown. In the afternoon's other | :05:19. | :05:20. | |
games Everton face Swansea in the early kick off at 1.30PM and | :05:21. | :05:23. | |
Sheffield United play Nottingham Forest at 3PM. | :05:24. | :05:34. | |
Last up, we love to bring you daft animal stories and today is no | :05:35. | :05:38. | |
exception. This water loving piglet called Kama loves to go surfing with | :05:39. | :05:42. | |
his owner in America. Here he is catching the waves at Hawaii's Sandy | :05:43. | :05:45. | |
beach. Kama's love of surfing started when he used to swim with | :05:46. | :05:49. | |
his owner in a pool in the back garden, and look at him now. | :05:50. | :05:55. | |
That's all from me, Newsround's back right here in about half an hour. | :05:56. | :05:58. |
