Can we ever stop the hurricane for the image in the title article? for the title article

Neutralizing a hurricane may seem like a dumb idea when it barrels over the ocean, but if we reject seemingly dumb ideas we could ever go to the moon, you know? Yes, Hurricanes are impossibly huge and powerful-But I think so, Goddam is the collective ingenuity of the human race! And see, we’re really going to need something that’s given the trick Climate crisis There are stores. As it turns out, this week Jizz asks Respondents, decades ago, were right when mainstream scientists were working hard on this issue. To learn about their exploits and other adventures in hurricane-extinction, see below.

When confronted with an irresistibly strong and dangerous force of nature, the first method is often to find a definite and simple solution. Unfortunately, the most commonly proposed approaches can be anything other than simple. Starting from the basics, a tropical cyclone (it officially turns into a hurricane only when its wind speed is over 74 miles per hour) is a huge, churning, whirling storm that runs on heat provided by the warm tropical oceans, often causing a particularly strong wind. Is. And the relatively cloudless “eyes” around the center of the “eye wall” of rain.

It seems plausible that an explosion of sufficient energy could disrupt a hurricane’s operation … unless you consider the scale involved. The heat emitted during a hurricane can be compared to a 10-megaton atomic bomb exploding every 20 minutes, a quantity that is far greater than the average annual energy consumption of the entire human race. Even with the significant public health problems that result from frequent nuclear crashes, the logistics involved in expending so much energy more than once in each storm season will be unprecedented.

What about that warm ocean water? Surely if we can eliminate the source of fuel, these huge storms will lose their destructive power. Theories surround everything from the Arctic to cold, deep water churning to pulling ice cubes to place a damper on a near-surface heat source. Again, the logistics involved are deeply unreasonable: NOAA’s Atlantic Oceanographic and Meteorological Laboratory estimates that more than 7,200 square miles of sea will be affected, even if the hurricane affects the eye wall area for 24 hours of its life. Taking into account track uncertainty, the cool patch will cover over 24,000 square miles. Even if one could find a way to quickly place and discard a large enough ice cube in that particular 24,000-square-mile bowl of soup, the effects of the sudden cold on marine life would be absolutely devastating. In the light of many observations of sea surface temperature rise (and estimates of the continuous rise of climate models), any method based on sea surface cooling may become less feasible over time.

There have been attempts to change hurricanes in the past (see Project STORMFURY in the mid-20th century, for example), but the complex dynamics of hurricane growth make it difficult to isolate any test results for sure; As an example, what initially seemed to be “successful” in some attempts to sow the seeds of a tropical cyclone turned into a coincidentally timely moment of weakening Hurricane Iwall, a normal part of its life cycle (and, often, subsequent intensification!) Like the National Hurricane Center The focus of the agencies is then on improving our physical understanding and forecasting of hurricane tracks and the intensity for the best decision makers and the public. For the rest of us, the emphasis should be on adaptation, mitigation, education, and ensuring that those who are most at risk during adverse weather have access to the resources needed to stay safe.

Nowadays, hurricane change is almost considered as a kind of science. But that was not always the case. Beginning in 1962, Project Stormfury was a 22-year-long experiment led by some of the biggest names in hurricane science. It was very mainstream.

The idea behind Project Stormfury was that you would basically try to sow the original clouds outside the hurricane and try to strengthen it to weaken the inner core. But it was hard to estimate how successful these efforts were, because, for one thing, we don’t have a control group – we can’t say, “Okay, what would have happened if we hadn’t done it?” And say you sow a hurricane. And it actually works – would the storm have weakened anyway? Would it have been weaker More What if you left it alone? There is really no way to know.

Scientists are still working on this question, but I’m not optimistic. People have talked about trying to cool the water, but it will probably have a huge impact on marine life, you also need to start operations a few days in advance and know exactly where the hurricane is going before you get there.

Hurricanes are big, and they are extremely powerful, and the amount of energy they generate is far greater than we can produce. You will remember that our last president suggested defeating a hurricane, but not even an atomic bomb can compete – you will only get a hurricane that burns at night.

I’m actually the guy who killed Stormfury. It’s sort of a dubious difference.

Stormfury was an attempt to weaken the tropical cyclone. The idea was to sow hurricane seeds with silver iodide to create a new outer eye wall and reduce the strongest wind in the original inner eye wall. It was a husband and wife team project, Joan and Bob Simpson. Bob Simpson is the man who founded the National Hurricane Research Project in the mid-1950s, and in this case we are all indebted to both of them.

When I was in the Navy, I used to fly raccoon over the Pacific Ocean; I knew what the radar signature of an unchanging cube-centric Ival cycle was like. Eventually I was wound up in the Hurricane Division, where I noticed that the hurricanes modified by Project Stormfury – which were sown with iodine – behaved like unchanged ones when I was over the Pacific Ocean. Some colleagues and I put together a paper that made a good case that the Simpsons thought what they had done with Stormfury was actually the result of natural change.

Usually, in science, a debate like this would be controversial – it would be debated year after year. But our paper almost ended the conversation. Joan was a very burning person and she never forgave me. Which is a shame, because I was a big fan of him.

Due to the geometry of the Earth-Sun relationship, the Earth receives the lion’s share of incoming solar radiation (sunlight) in its lower latitudes, i.e. in the tropics. Due to this uneven distribution of sunlight, the tropics are warmer than the upper latitudes. The Earth’s climate system redistributes tropical heat to higher latitudes through ocean and wind currents. Various processes that help redistribute this heat include tropical cyclones, aka hurricanes, and typhoons. Heat redistribution from low to high latitudes is a key feature in determining regional climates and global conduction patterns. Considering the role tropical cyclones play in this process, it seems foolish to stop hurricanes on their tracks or reduce their strength.

From a global redistribution of the heat perspective, perhaps a “safer” goal would be to relocate tropical cyclone tracks to limit their interaction with land and therefore human and man-made infrastructure. However, the strength and scale of tropical cyclones are infinite, and therefore their ability to engineer changes in their intended course is questionable. A somewhat similar example of the challenge of storm track migration can be found in mid-latitude, where ethnographic climate change can shift intermediate storm tracks to a slight pole in some areas – a rather modest change for the now uninterrupted but now running 150 years of climate engineering “testing.”
