Why there are more tropical cyclones in Northern hemispere?
There are nearly 80% major tropical storms that occurs in Northern hemisphere,between 0 to 30 degree north latitudes. Various answers are given ,which you can find anywhere.
However, my explanation is as follows
Besides warm water 27 degree Celsius main reasons ,I think ( which is debatable and not approved by any authorities ) are
1) Due to coriolis phenoma wind in northen hemisphere moves South west /anticlockwise,between 0 to 30 degree north
2) Due to 23.5 degree NE tilting of Earth this direction practically becomes East to west .( see diagram)
3) Sun and Moon ( zenith positionon Earth) move from East to west).Hence low tide area shifts from East to west.Hence the air flows practically from East to west( in Northen hemisphere between 0 to 30 degree N)
4) As the low tide area shifts East to west,the air rushing to fill the partial vaccum also moves from East to West
5) Both ,natural wind and tidal wind help each other ,both moving East to West ,as seen in diagram,in Northern hemispere, between o to 30 degree north
6) The wind shear velocity ,in this case help the strom to form ( both ,natural wind and wind formed to fill partial vaccum,moving in same direction,East to west)
7) The air moving over warm oceans gethers potential energy from ocean.
Thus 80% tropical cyclones in Northern hemisphere between o to 30 degrees north
Though southern hemisphere have all other prerequisites like ,warm water ,( actually more and vast oceans) required temperatures between Equator to 30 degree South ,there are only 20 % cyclones in southern hemisphere.
From the diagram it is clear that ,coriolis effect wind is almost northward ,and both contradicts each other,in southern hemisphere
The natural wind at Southern hemisphere between 0 to 30 degree South ,due to 23.5 degree tilting of Earth (NE ), is practically northward with respect Sun and moon( see diagram)
Thus in short ,the air rushing to fill partial vacuum, the 23.5 degree NE tilt of Earth , warm water and Corrolaries phenomenon are all responsible for more cyclones in Northern hemisphere
The main reason of more tropical cyclones in Northern hemisphere is the twenty three and half degree tilting of Earth to NE and nothing else
