President Trump has suggested multiple times to senior Homeland Security and national security officials that they explore using nuclear bombs to stop hurricanes from hitting the United States, according to sources who have heard the president's private remarks and been briefed on a National Security Council memorandum that recorded those comments.
Behind the scenes: During one hurricane briefing at the White House, Trump said, "I got it. I got it. Why don't we nuke them?" according to one source who was there. "They start forming off the coast of Africa, as they're moving across the Atlantic, we drop a bomb inside the eye of the hurricane and it disrupts it. Why can't we do that?" the source added, paraphrasing the president's remarks.
Trump also raised the idea in another conversation with a senior administration official. A 2017 NSC memo describes that second conversation, in which Trump asked whether the administration should bomb hurricanes to stop them from hitting the homeland. A source briefed on the NSC memo said it does not contain the word "nuclear"; it just says the president talked about bombing hurricanes.
White House response: A senior administration official said, "We don't comment on private discussions that the president may or may not have had with his national security team."
The big picture: Trump didn't invent this idea. The notion that detonating a nuclear bomb over the eye of a hurricane could be used to counteract convection currents dates to the Eisenhower era, when it was floated by a government scientist.
About 3 weeks after Trump's 2016 election, National Geographic published an article titled, "Nuking Hurricanes: The Surprising History of a Really Bad Idea." It found, among other problems, that:
Atlantic hurricane season runs until Nov. 30.

In 1966, a nuclear explosive was detonated at Urtabulak gas field in Southern Uzbekistan in order to extinguish a gas well fire that had been burning for almost three years and had resisted numerous attempts at control. The gas fountain, which formed at pressures of almost 300 atmospheres, had resulted in the loss of over 12 million cubic metres of gas per day through a 200 mm casing – enough to supply a city the size of St Petersburg. Two 445 mm holes were drilled that aimed to come as close as possible to the well at a depth of about 1500 metres in the middle of a 200 metre thick clay zone. One of these came to within about 35 m of the well and was used to emplace the special 30-kiloton charge which had been developed by the Arzamas weapons laboratory. Immediately after the explosion the fire went out and the well was sealed.
This was the first of five PNEs used for this purpose, and all but one was completely successful in extinguishing the fire and sealing the well. No radioactivity above background levels was detected in subsequent surveys of any of the sites.

Just a couple of follow-ups based on hopefully not too foggy a memory:
1. If one calculates the latent heat release rate from a large
hurricane (so take an area of the rainfall, and a rainfall rate of
say 6 inches in a day over that area), one can then compare to the
energy of a nuclear weapon, just to get a sense of relative
magnitudes. When I did so several decades ago, as I recall that
the rate of latent heat release (as one metric of the energy a
hurricane is processing) was equivalent to a few megatons per
minute (now this energy is not all dissipated as most is
transformed into rising motion that returns as heat when air
elsewhere is pushed down, but even if a few percent goes to
friction loss with the surface, one gets a sense of why the
destructive path can look like a war zone). The size of most
nuclear weapons in current arsenals is perhaps at most a couple of
hundred kilotons, and in any case, a megaton explosion would take
its energy well up into the stratosphere. So it is really hard to
see how using even a dozen nuclear explosions could do much of
anything, even as a storm was forming, especially as it is heat
that is driving the intensification of the storm. And one would
have no idea what the outcome would be, if anything at all--and
since pretty much each storm system is unique, there really is no
good baseline. Basically, the idea is ridiculous.
2. I once got invited to Teller's office to answer whether nuclear explosives could be used to break the California drought in the mid-1970s or so. I rough estimated the energy involved in the drought (foregone latent heat release), ocean temperature anomaly said to be diverting the storm track, and month-long effect of the excess albedo due to midwestern snow cover that was also suggested to be a cause--each came out at something 10**21 calories. A megaton is 10**15 calories. So even if one could imagine a 1% trigger to change things, it was still 4 order of magnitude. Teller was said to be an order of magnitude thinker--I put these numbers on his blackboard and that was the end of that idea (not his, but one of his proteges--and not Lowell Wood, but ET did want an analysis).
3. On the Alaska harbor idea, the book about it is "The Firecracker Boys", and the idea was to make a good harbor as the basis for economic development. Environmental analysis pretty quickly showed the risks to the food chain and health as radionuclides got taken up in moss and then the reindeer ate the moss and then the people ate the reindeer, etc. It was study of this and a few other such ideas that led, as I understand it, to formation of the Office of Biological and Environmental Research (or some similar name) within the AEC. That office later became the Office of Health and Environmental Research in DOE and got started on climate change research back around 1978. Also, much of the research done on radionuclide paths to people, etc. turned out to be really useful (in addition to making clear the risks of using nuclear explosions to make a harbor) for figuring the heavy metal dose to people from such pollutants as mercury emissions from coal-fired power plants. So, not in vain.

Hi Alan--On your reminiscence, if one exploded the nuclear
weapon(s) out over the ocean so there was not a dirt surface that
would be radiated and lofted into the atmosphere as radioactive
fallout, I'm not sure that much of the radioactivity would have
ended up on particles and then stayed aloft given the torrential
rain. Perhaps radioactive gases might have been created, but they
would have been rapidly lofted up in the air flow and carried out
the top of the system such that the storm coming ashore somewhat
later would not have been likely to have much of the radioactive
gas cloud in it--any radioactive gases that were in the atmosphere
I would think would have been thrown out the top and been
dispersed over a very wide area (greatly diluted, but very broadly
spread). In any case, good they did not give the idea a test.
As I recall, the first order of magnitude estimate I did on hurricanes was in 1965 for a seminar class taught be Chuck Leith (https://www.aip.org/history-programs/niels-bohr-library/oral-histories/31392) and Mike May (https://cisac.fsi.stanford.edu/people/michael_m_may) on Geophysical and Astrophysical Hydrodynamics (Mike was soon thereafter made Livermore Lab director and may have been Lab director the summer you were at Livermore). As to the calculation, I divided the amount of rainfall from a reasonably sized hurricane by the use of water by New York City, and finding a reasonable hurricane's daily rainfall amount would supply New York City with water for 5 years. Tropical cyclones put out a lot of rain.
Best, Mike

Hi All
I have sent the attached note on suppressing hurricanes and typhoons with Lathams' idea for marine cloud brightening to a number of you with a request for corrections or different input assumptions. Perhaps this a good time to repeat the request.
If we already had the fleet of spray vessels it would be too late for this year. We should have started last November and tracked sea surface temperatures to some value agreed by endangered countries.
It would be useful if they could start the discussions now to be ready for years ahead.
