Mid-latitude storm system : The counter-clockwise swirl shows that this is a northern hemisphere storm . Let 's assume the current in the loop transverses it clockwise ; if it goes counter-clockwise , you can repeat the argument , but with the directions reversed . ) Turn it counter-clockwise about two turns from the resistance point , then initialize again . Midlatitude storm system : The counter-clockwise swirl shows that this is a northern hemisphere storm . During group gaiting , the 4-H ’ er and dog will always move counter-clockwise around the ring . The first component is parallel the direction of wave propagation , and the second component is perpendicular to the first ( while looking down it is 90 counter-clockwise from the first component ; i.e ., in a right handed coordinate system with the positive vertical axis pointing upward ) .
