Ball Lightning

A small square region on the big screen displayed a missile roaring off the launcher and into the sky. The camera tracked it, showing its thin white tail painting a giant parabola across the sky. Roughly one minute later, the missile crossed the peak of the parabola and began to descend, and after one more minute, at an elevation of roughly five hundred meters, it exploded in a blistering fireball that looked like a blooming rose against the sky. In the section of the screen showing the atmospheric disturbance, a rapidly expanding crystal ball appeared at the spot marked by the red circle egg. Then the transparent sphere transformed and disappeared, its position filled in by the chaos of the disturbance. The red circle vanished, and the alarm ceased. Dr. Ross declared that the egg had been annihilated. This was the ninth egg wiped out by the “Tornado Hunter” system that day.

Dr. Ross explained: “You all know that tornadoes are usually born out of strong thunderstorms. When the hot, wet air of a thunderstorm rises and crosses the upper layer of cold air, it gradually cools. Water vapor condenses into raindrops or hailstones, which are borne downward when the cooled air begins to sink, only to be pushed back up again by factors like the warm lower layer and the rotation of the Earth. Ultimately, these layers form a tornado. The process of tornado formation is unstable, but the sinking of the cold air represents a critical energy flow. This mass of sinking cold air is the heart of the egg. The Tornado Hunter system fires a missile carrying an oil firebomb that detonates in a precision strike on the sinking cool air, instantly releasing an immense amount of heat energy that increases the temperature of the mass of air and breaks the tornado’s formation. It strangles it in the cradle.

“As we’re all aware, the technology for missile strikes and oil firebombs is not new. This isn’t really a precision strike, either, since the precision we require is a level less than is used for military uses. That lessens the cost. What we’re using are all obsolete, decommissioned missiles. The key technology in the Tornado Hunter system is Dr. Chen’s atmospheric optical detection system. That’s the innovation that allows us to determine the advance positioning of the egg. It’s what makes the artificial destruction of tornadoes possible. Let us pay him our deep respect!”

The next day, Oklahoma City, the state capital, made me an honorary citizen of the city. When I accepted the citation from the governor, a young blonde woman presented me with the Oklahoma state flower, mistletoe, which I had never seen before. She told me that a tornado had taken her parents the previous year. It had been a terrifying night. An F3 tornado had ripped off the roof of her house and flung everything inside more than a hundred meters into the air. She had only survived because she had landed in a pond. Her account reminded me of the night I lost my parents, and gave me a sense of pride in my work. It was this kind of work that finally rid me of the shadow of ball lightning, and let me start on a new life in the sun.

After the ceremony, I congratulated Dr. Ross. Even though I had been the one to make the breakthrough in forecasting tornadoes, they had been the ones who ultimately conquered them.

“It was TMD that finally conquered tornadoes,” he said absently.

“Theater missile defense?”

“That’s right. It was adopted practically without modification. It was only a matter of replacing the system’s incoming missile identification module with your egg positioning system. TMD seems purpose-built to destroy tornadoes.”

I realized then that the two were indeed similar: they both automatically identified targets, and then used guided missiles for precise interception.

“My original field of study had nothing to do with meteorology. I was in charge of TMD and NMD software systems for many years. When I realized that the weapons systems I’d developed could be used to benefit society, I felt a joy I’d never had before. Dr. Chen, you have my special thanks for that.”

“I feel the same way,” I said sincerely.

“Swords can be made into plowshares,” Ross said. But then in a much lower voice, he added, “But some plowshares can be cast back into swords. Weapons researchers like us sometimes have to accept blame and loss for this in the course of carrying out our duties…. Can you understand that, too, Dr. Chen?”

I had heard similar words from Gao Bo, and so I nodded silently, but my mind grew wary. When he said “us,” did he include me? Did they really know about the work I used to do?

“Thank you. You have my sincere gratitude,” Ross said. He was looking at me with a peculiar expression, which betrayed a glimpse of sorrow. Later I realized I was thinking too much, and that his words had nothing to do with me. I only learned later what his expression really meant.

I was among the final group of visiting scholars to go abroad. Ten days after I returned home, war broke out.
