Imagine being in the middle of a category five hurricane, one of the most powerful storms on Earth. These storms can stretch up to a thousand miles and unleash heavy rains, massive waves, and winds over 160 miles per hour. Hurricanes, also called typhoons or tropical cyclones, form over warm tropical oceans, gathering heat, energy, and moisture. The warmer the ocean, the more intense the hurricane can become. With climate change warming our oceans, these intense storms might become more frequent.
To better predict and understand these storms, scientists have created a machine that can simulate hurricane conditions indoors. This helps them study hurricanes safely and improve their predictions, which can save lives.
At the University of Miami, there’s a special lab called the SUSTAIN wind wave laboratory. This lab can create conditions similar to a category five hurricane. It uses a giant wind tunnel and wave machine to study how the atmosphere and ocean interact during a storm.
Brian, a scientist at the lab, explains that they can generate winds up to 155 miles per hour, which is extremely dangerous. The lab uses a powerful fan and wave paddles to create these conditions, allowing scientists to study hurricanes in a controlled environment.
One of the biggest challenges in hurricane prediction is determining how intense a storm will become. Sometimes, hurricanes can rapidly intensify, like Hurricane Maria, which went from a category one to a category five in just 18 hours. This leaves little time for people to prepare and can lead to devastating consequences.
The SUSTAIN lab helps scientists understand how hurricanes develop. As the storm’s winds blow over the ocean, they create waves. These waves can actually slow down the storm’s growth by extracting energy from it. This knowledge helps improve prediction models, giving people more time to evacuate and stay safe.
While we can’t stop hurricanes, we can use engineering to reduce their impact. For example, sea hives are artificial structures that act as breakwaters, weakening waves before they reach the shore. This can help protect coastal areas from storm surges.
As our planet and oceans warm, it’s crucial to learn as much as we can about hurricanes. This knowledge helps us minimize risks, save lives, and adapt to climate change. If you live in a hurricane-prone area, be thankful for the scientists working to understand these storms so you don’t have to face them unprepared. Stay curious and informed!

This is what it’s like to be in a category five hurricane. The winds and waves here are incredibly powerful. These are Earth’s most powerful storms, spanning up to a thousand miles and capable of devastating coastal areas with heavy rains, surging waves, and sustained winds of more than 160 miles per hour. Hurricanes, also known as typhoons or tropical cyclones, form over warm tropical oceans, drawing up significant amounts of heat, energy, and moisture. A hurricane’s intensity depends on how much energy it can extract from warm ocean water. As climate change affects our environment, the oceans have warmed, increasing the potential for more intense hurricanes to occur more frequently.
To better predict the destructive impact of these storms and save lives, scientists have developed a machine that can create severe hurricane conditions indoors.
Hey, everyone, Joe here. While we can’t predict exactly when it will happen, at some point in the future, a hurricane will make landfall near where I am standing right now. This is a potentially disastrous scenario because this southern tip of Florida is home to over 6 million people. On August 24th, 1992, Hurricane Andrew made landfall 25 miles south of Miami, bringing a 16-foot storm surge and 165-mile-an-hour winds, resulting in $25 billion worth of damage and over 40 fatalities. Andrew was a category five storm, the highest rating of hurricane intensity. Damage from a category five storm hitting Miami today could easily exceed $100 billion. With more people and buildings near the coast than ever before, the potential for devastation is significant.
Scientists have become proficient at predicting the paths that hurricanes will take, but predicting their intensity is much less accurate. The models simply aren’t refined enough. To create better tools for these predictions, scientists need to study hurricanes in detail. They have developed advanced tools to study hurricanes using remote instruments, flying into them, and even observing them from space. However, many mysteries require close examination of storms and data collection at very small scales. Unfortunately, studying the world’s most powerful storms up close can be dangerous unless you can create a hurricane in a controlled environment.
Brian: Hi Joe. This is the SUSTAIN wind wave laboratory. SUSTAIN stands for surge, structure, atmosphere, interaction.
Joe: This has to be one of the coolest scientific tools to work with. Is that right?
Brian: Yes, it can still be quite impressive to watch, even after seeing it run hundreds of times.
Joe: The SUSTAIN lab at the University of Miami is a giant wind tunnel and wave machine that allows scientists to study the interaction between the atmosphere and the ocean, simulating conditions up to category five hurricanes.
Brian: A category five storm is defined by wind speed, which is about 155 miles an hour sustained winds. That’s a wind that most of us have no experience with, and it is extremely hazardous to life and property.
Joe: And you can create that in here?
Brian: Yes, we can replicate the conditions equivalent to a category five hurricane. This is the largest structure in the world capable of generating such wind speeds over water.
Joe: Is there a big button that just says “hurricane”?
Brian: We have a lever that essentially activates the system.
Joe: I really want to turn this thing on. Do you think we can do that?
Brian: Yes, I think we can do that.
Joe: I’m really looking forward to this.
Brian: For the wind. We have a simple process to follow.
When the lever is activated, a 1500 horsepower fan draws in air from outside, compressing it to increase its velocity before it enters the tank. The giant paddles then push on the water to create waves that flow across the surface.
Brian: This is a Wavemaker drive that controls the wave patterns. It uses algorithms to generate electrical signals that dictate how the waves will move.
Joe: So you can create custom waves?
Brian: Exactly.
Joe: Have you ever put tiny surfer toys in there?
Brian: We have, actually. We once put in some little yellow ducks.
We placed a camera inside the hurricane tank to simulate what it would be like to be in a category five hurricane.
Joe: Let’s make a hurricane.
Brian: We’re starting with just wind, and as we reach full wind speed, we’ll activate the waves as well.
Joe: I think it’s going to get hard to hear us in a minute. Can you estimate how fast this is right now?
Brian: It’s already at full category five levels.
Joe: Wow. I’m glad we’re out here and not in there.
Seeing category five hurricane winds from just feet away was impressive and a bit intimidating, considering the power of those winds.
One of the key gaps in hurricane prediction has been intensity. This can be a significant issue if a storm intensifies rapidly. For instance, Hurricane Maria intensified from a category one to a category five storm in just 18 hours, leaving little time for those in its path to prepare, ultimately causing over 3,000 deaths in Dominica and Puerto Rico. Hurricanes can escalate from dangerous to historically destructive levels in a very short time. Being able to predict whether a hurricane will be powerful several days in advance could allow for more time for evacuation and save lives.
This storm machine is already helping scientists better understand how hurricanes develop. As a hurricane’s winds blow over the waves, the rough surface of the ocean exerts drag on the storm, extracting energy from it. What researchers have found is that as a hurricane strengthens, rougher seas and larger waves can actually prevent storms from growing too quickly.
Brian: When you blow the wind, it creates huge waves. The energy from the wind goes into making those waves. As the winds become very intense, the interaction with the waves changes.
Joe: It feels like if I were in a car going really fast, my tires would stop gripping the road as well as they did at lower speeds.
Brian: Exactly. When you reach a certain speed, the friction can diminish.
Findings like these are helping scientists develop more accurate models to predict when hurricanes will rapidly intensify. What makes this hurricane lab special is the ability to observe both winds and waves as an interacting system.
Brian: If we didn’t have the waves, we wouldn’t be able to study many important problems. People often think of storm surge in terms of height, but that doesn’t account for the wind pushing water toward the shore.
Water is significantly heavier than air, and when waves hit structures, the force is much greater than just the wind alone.
While there are many ideas for mitigating hurricanes, such as using bubbles to cool the ocean or other extreme measures, it’s likely impossible to stop a hurricane. However, we can use engineering to enhance resilience and draw inspiration from nature.
Brian: These are called sea hives, designed to act as artificial breakwaters. They help dissipate wave energy offshore, making the waves weaker when they reach the shore.
In summary, our planet is warming, and so are our oceans, which increases the potential for stronger storms. It’s essential to learn as much as we can about hurricanes to minimize risks, save lives, and adapt to the effects of climate change.
If you live in an area that could be affected by a hurricane, be grateful for the scientists studying these storms so that you don’t have to face them directly. Stay curious!
