Kelvin Waves

2010-10-15T11:12:00.002+02:00

Hi

I'm back again, as you are seeing I'm not really a blogger. But today I decided to write in my blog about a phenomena I'm working with: Kelvin Waves. You have probably not heard about them before, but they are important in the oceans. The Tide is actually linked through Kelvin waves.

To describe these waves, I will use the tide as en example. When tides is getting high, it will disturb the sea-surface, that itself creates this Kelvin Waves. These waves will travel along the coast at the right side in the Northern hemisphere and at the left side in the Southern hemisphere. These waves will also travel along the coast and creates a perturbation we could also call a tide. Because of that ocean basins are big, we rarely are seeing this Kelvin Wave propagating a whole revolution before the tide is turning, if that happened you will getting the both stages of the tide . But you can actually see that at some island that has the right length to do so.

Hope you liked it and please comment about what you are thinking about it.

Weather School Part 3 : Twister or Tornadoes

2009-10-24T14:28:00.004+02:00

Hi

I'm here to update my blog, I haven't updated it for a while because of that I haven't found something interesting to talk about. So today I will continues my Weather School with something that many thinks is interesting, Twister or more commonly named Tornadoes.

A tornado is a rapidly rotating column of air, which is contact with the ground. This rotationg column needs to have a suiffcient rotating before its called a tornado. If you have a tornado you should have a convective (strong upward winds) storm in the vincinity, either it's hanging from or positioned beneath the base of the cloud. It's the atmospheric pressure who defines how the tornado looks like and the damaging wind is extended outsided the outline of the 'tornado cloud'. Even if we doesn't got any cloud, we still can have a strong wind.

How a tornado really does work is hard to know, but they are still pretty amazing and beutifull. Something interesting is that the updraft in a tornado is many times stronger then the graviation accelration which implis tha we got strong pressure difference vertically.

Like usally please comment and give me your thought about this entry.

Weather School Part 2 : Weather System Part One

2009-08-19T20:53:00.007+02:00

In the latest part, I tried to explain how High and Low pressure system works. In this part I will continues on the same path and go deeper into them. A High Pressure system has often nothing interesting to point out, instead we will focus on storms aka a low pressure system. The only interesting with a high pressure system is that is usually cloudless.

Low pressure system can deepen or developed as it continues its path, the mean path is towards the east ( UK to Sweden to Russia) in the northern hemisphere. When the system deepens the winds grow stronger and the clouds gets bigger. In the centre of the system the winds goes upward and clouds forms. Why does the wind go up-wards ? The answer to that question is not easy to explain in layman terms, but I will try: The storm system need to have a mass-balance. When new air moves into the centre, the system needs to send away some to preserve the mass-balance.

A tropical cyclone is also a low pressure system, but is still a little different and I will describe them in the next Weather School

If you wants to know more about low-pressure system, you only need to ask in a comment.

A Fan Fic Review

2009-08-09T21:34:00.007+02:00

It was a long ago since I updated my blog, I haven't find something I want to write about. In this post I have decided to talk little about a great Harry Potter Fan Fic I are reading. This is a series with 2 of 7 parts (I think) posted.

This fan fics is about a girl named Alexandra Quick, who learns that she's a witch. She had already fount out that she could do stuff, but what she didn't know was that her father is a wanted man. Her father left her mother when she was young and doesn't know anything about him...

In the first part, we are following her through her first year were she learns more about her father and why he is wanted..

In the second part, she learns about a 'dark convent' who want her to join her and she also discovers 'The Lands Bellow'

I really likes these stories because of the new world the author has created, new characters, new places and lot of new magic stuff. Another great thing is that you doesn't need to have read the Harry Potter series. Everything you need to know is in these fan fics.

The first part can be found: http://fanfiction.mugglenet.com/viewstory.php?sid=79048

The second part can be found: http://fanfiction.mugglenet.com/viewstory.php?sid=81783

Until next time...

Hope you liked this post!

Chuck - One of the best Show on Telivision

2009-07-08T20:16:00.006+02:00

Hi in this week's post I have decided to present on of my favourite show, Chuck. This show isn't regular show, we have comedy, action AND romance. This unusual mixture is what make this show so interesting, if you like romance you will find this show very interesting with a BIG romance. If you are a action lover you will also find this show interesting who has many great action scenes.
---------------------
If you mixture action and romance with comedy as a foundation you will get Chuck. Is unusual when a show mixture comedy with action and romance and this particular "blend" is very giving. But I think many of the fans has beginning to love the story between Chuck and Sarah.
-----------
If you find this post about Chuck interesting you maybe want to know something about the plot of the show, so here is a recap about what Chuck is about:

Chuck Bartowski is a computer geek working in an electronics store (Buy More). He doesn't particular like working there, he is a Nerd Herder supervisor (fixing computers). He's living with his sister and isn't particular good with women's he is till not over is ex-girlfriend who dumped him about five years ago.

One evening he gets a e-mail from his old college buddy Bryce, when he opens it he gets all the government secrets downloaded into his brain.
It doesn't take long for the government to find out who has their secrets and NSA and CIA assignees two agents to protect Chuck. The beautiful Sarah Walker (CIA) who is posing as Chuck's girlfriend and John Casey (NSA) who is Chuck's co-worker and neighbour. As these agents is protecting Chuck they learns to liking him and see that he really is valuable.

I hope you find Chuck interesting and start to watching it. In the US you can watch Chuck on hulu.com and NBC.com. If you aren't living in the US like me, sadyly you need to buy or lend a copy of the DVD to see this show.

If you wants to learn more about Chuck you can visit http://chucktv.net/ or http://www.nbc.com

Weather School Part One: Pressure

2009-07-01T23:38:00.011+02:00

Welcome to my first part of my own little weather school, I will start with something easy like pressure.
-------------------------------------------------
Pressure is measure of how much force a object has against a surface. The earth atmosphere has a standard pressure who is 1012 hPa. When a meteorologist are talking about high pressure or High they are talking about a region with a higher pressure then in the rest of the vicinity.

The fact of that high pressure often are connected with a beautiful weather is because of the vertical wind (downward) who create a region who has less clouds then a region with a standard pressure.

A low pressure is often connected with cloudy and rainy weather, this is also because of the vertical wind (upward) who here is contributing to the genesis of clouds.

If you has some question or want to correct something or if you like this particular entry please comment.

My First Blog Entry

2009-06-30T07:36:00.000+02:00

Welcome to my brand new blog about everything! My goal is to write at least one entry per week about something I think it's interesting. I start with telling you about a wonderful show named Chuck, I'm participating in ChuckMeMonday, there we are re watching Chuck and twitter about it. Today was we watching episode 5 Chuck vs The Sizzling Shrimp, it was an awesome episode with many great scenes.
