Hoogte van de sfeer boven de polen, de evenaar en boven Nederland. Onderdelen van de sfeer. Grenzen van de sfeer


Boven de poolgebieden is de troposfeer 8 kilometer hoog. In Nederland is de troposfeer 10 kilometer hoog. In de tropen is de troposfeer 16 kilometer hoog. Het onderste deel van de troposfeer heet de planetaire grenslaag (PGL) of ook wel atmosferische grenslaag. Boven de PGL heb je de vrije atmosfeer. De bovenkant de van de troposfeer heet de tropopauze. Deze vormt de grens tussen de troposfeer en de volgende laag: de stratosfeer. Kenmerk van de troposfeer is dat de temperatuur met 6,5 graden Celsius afneemt als je 1000 meter hoger komt. In de stratosfeer neemt de temperatuur juist weer toe. De temperatuur boven in de troposfeer is -55 graden Celsius.

De temperatuur daalt omdat de lucht van onder verwarmd wordt door de aarde. De aarde weerkaatst namelijk het warme zonlicht. Die warmte wordt opgenomen in de lucht. Hoger in de lucht dringt minder straling door en wordt ook minder opgenomen omdat de luchtdruk afneemt. In de tropopauze verandert de temperatuur bijna niet. Vliegtuigen vliegen net onder de tropopauze. De motoren van de vliegtuigen werken beter bij koudere temperaturen.

De luchtdruk onder in de troposfeer is ongeveer 1 bar (om precies te zijn 1013 millibar) groot. Tot 4000 meter hoogte neemt de luchtdruk gemiddeld per 8 meter, 1 millibar af. Op 4000 meter hoogte is de luchtdruk dus ongeveer 613 millibar. De lucht is hier ijl. Ademen gaat daardoor moeilijker. Troposfeer [bewerken] Planetaire grenslaag

De planetaire grenslaag is vanaf het aardoppervlak tussen de 200 meter en 2 kilometer dik. Dat is afhankelijk van het soort aardoppervlak en het tijdstip van de dag. Kenmerk van de PGL is dat het veel invloed heeft op het weer. Dat doet het op verschillende manieren. De wind die langs het aardoppervlakte waait ondervindt wrijving van het aardoppervlak. Hierdoor ontstaat turbulentie. De aarde straalt de warmte die ze krijgt van de zon weer uit in de troposfeer. Zo ontstaat ook thermiek. De zonnestralen verwarmen op die manier de lucht. Vocht dat verdampt van de bodem en planten zorgen voor vochtigheid in de lucht. De rode streepjeslijn geeft de bovenkant van de planetaire grenslaag aan.

Het woord troposfeer is afgeleid van het Griekse woord tropos. Het Griekse woord tropos betekent "draaien" of "mengen". Zoals je net las is de lucht in de onderste laag van de troposfeer druk in beweging en is het daarom een passende naam.


[bewerken] Feiten over de troposfeer 

   * 80 procent van alle luchtmassa vind je in de troposfeer. Dit komt door de zwaartekracht van de aarde;
   * De lucht in de troposfeer zorgt ervoor dat we kunnen ademhalen;
   * de lucht in de troposfeer bestaat voor al uit stikstofgas en zuurstofgas;
   * doordat er veel waterdamp in de troposfeer zit, ontstaan hier ook de meeste wolken en neerslag.

Een tornado.

Een tornado is een wervelwind. Een tornado lijkt op een draaikolk. Het is een trechtervormige slurf onder een wolk (cumulonimbus en soms cumulus) die contact maakt met de grond. Tornado's hebben verschillende vormen maar ziet er meestal uit als een wolk in de vorm van een trechter. Er om heen vliegen brokstukken. De windsnelheid in de meeste tornado's is minder dan 177 kilometer per uur. Ze zijn ongeveer 80 meter breed en leggen een paar kilometer voordat ze verdwijnen. De zwaartste tornado's halen windsnelheiden van 480 kilometer per uur, zijn meer dan drie kilometer breed en leggen meer dan 100 kilometer af. Behalve op de Zuidpool zijn er op elk werelddeel al wel tornado's voorgekomen. De meeste tornado's komen voor in Tornado Alley, een gebied in Noord-Amerika. In Amerika zijn zo'n 1300 tornado's per jaar. De meeste tornado's komen voor van april tot juni (het tornadoseizoen).

Tornado-alley, hoe donkerder de plek des te meer tornado's komen er voor.

Hoe ontstaat een tornado

De meest heftige tornado's ontstaan in een zware onweersbui. Zo'n onweersbui heet een supercel. Een supercel is een ronddraaiende onweersbui. In de onweersbui draait een wervelwind omhoog. Deze wervelwind (met een moeilijk woord mesocycloon)...


  1. Een tornado ontstaat als een koude lucht en een warme lucht elkaar ontmoeten. De koude lucht schuurt langs de warme lucht. De warme lucht word opgeladen en stijgt omhoog doordat de warme lucht is opgeladen is het een onweerswolk.
  2. Op dat moment komt de tornado. Als er een tornado ontstaat gaan de wolken rond draaien.
  3. Als ze heel snel draaien komt er een klein stuk omlaag.
  4. Nu worden de tornado's even magnetisch; de aarde is een magneet en de tornado is een magneet, daarom trekken ze zich naar elkaar.
  5. Als de tornado de grond aanraakt verwoest hij alles wat hem in de weg staat zoals houten huizen, auto's en bomen.

Soorten tornado's

Er zijn verschillende tornado`s zoals:

Tornadokrachten

Hoe sterk een tornado is meet je met de schaal van Fujita. Tetsuya Theodore Fujita was een Japanse weerkundige. Zijn schaal geeft aan hoe snel de wind waait in een tornado en voor hoeveel schade de tornado zorgt.

Kracht Snelheden Omschrijving Voorbeeld 1 Voorbeeld 2
EF0 64–117 km/h Lichte schade F0 tornado damage example.jpg EF0 tornado damage example.jpg
EF1 118–180 km/h Matige schade F1 tornado damage example.jpg EF1 tornado damage example.jpg
EF2 181–251 km/h Aanzienlijke schade F2 tornado damage example.jpg EF2 tornado damage example (1).jpg
EF3 252–330 km/h Ernstige schade F3 tornado damage example.jpg EF3 tornado damage example.jpg
EF4 331–417 km/h Zeer zware schade F4 tornado damage example.jpg EF4 tornado damage example.jpg
EF5 > 418 km/h Catastrofaal F5 tornado damage example.jpg EF5 tornado damage example.jpg

Er zijn verschilende tornadokrachten.
