I am pretty sure that a common-or-garden nuclear explosion would do the trick — BUT nuclear has to be OFF THE TABLE.
What we are trying to do is to create another area of low pressure to break up the atmospheric pressure patterns.
I did remember that there had been some work on this way back — and a quick Google on ‘Breaking Up Hurricanes‘ unearthed Project STORMFURY. But, they were NOT using explosives. I am thinking along the lines of the “Mother Of All Bombs” exploded over Afghanistan in mid-April 2017. Of course, you would do it while the storm was still over the ocean.
I am surprised we are not doing more research into this.
