Kinezek az ablakon, es téliszonyom van ;-) Unalmamban elovettem kicsit megint a gumicsontot, es meggugliztam a "+coriolis +tornado" kifejezeseket. Ket talalat az also oldalrol:

- A Tornado and Storm Research (Oxford Brookes University) media informacios oldalarol, a 10 Facts About Tornadoes resz elso pontja: "Tornadoes revolve both anticlockwise and clockwise, in both the northern and southern hemisphere. This is because they are too small to be affected by the Coriolis force - the way the Earth's rotation deflects winds around high and low pressure areas. However anticlockwise tornadoes are more prevalent in the northern hemisphere because some tornadoes develop from a larger circulation in a thunderstorm which can be affected by the Coriolis force." Rovid es tomor.

- A Problem of the Tornado: Mechanical Quandries oldalon kicsit bovebben is olvashatunk a jelensegrol. Igy kezdodik: "It's often stated (even by scientists) that the rotation of the earth, through the coriolis acceleration, is what gives a tornado its spin. However, if this were true, then there should never be a tornado in the northern hemisphere that turns in an anticyclonic sense. Yet such tornadoes do occur and they are not rare. For instance, in 1980 seven tornadoes struck Grand Island, Nebraska in a single day. Three of these turned in an anticyclonic sense.".

Egy magyar oldalon is olvashatunk temarol: "A tornádókról általában". A cikk nagy resze nincs ellentetben a fentiekkel, kiveve az ok-okozati lanc egyik darabjat, miszerint: "...Mivel ezt a teret magasabb légnyomású tér veszi körül, a levegő a Coriolis-erő szabálya szerint spirálisan megindul ezen tér felé, elkezd rotálni a felhőalap..."

Na most ezek alapjan en amondo vagyok, hogy a Lajos Tamás prof. (is) esetleg tevedhet... ;-)
