Honestly, this has to be the worst tropical basin in the world when it comes to tropical cyclones. The Atlantic, the east Pacific, the West Pacific (especially above the equator), the Indian Ocean and the Timor Sea all put it to shame, year after year, after year. Why is it so? Why is it, that 90℅ of the time conditions are so hostile for TC genesis in the Coral Sea yet in other Hurricane / TC hotspots around the world, such as those mentioned above, seem to be able to muster up at least some form of Typhoon / TC / Hurricane every year? I mean, I hope to come back to this thread after March and say well this year was an exception, but it still doesn't change the fact that the frequency of such events in the Coral Sea is so much lower than those around the world. There has to be a logical reason for this, I've still yet to come across one though.
By the way, I know people will blame the sub-tropical jet, the interaction with mid- lat troughs etc etc but that still doesn't explain why those other places don't seem to have as much of a problem contending with such conditions.
