This Is What Would Happen if China Invaded Taiwan

DMITRI ALPEROVITCH

The winter season in Taiwan—lasting from November till March—is great for surfers. It’s no Bali or Hawaii, as the size of the waves and their consistency may vary, but the Northeast Monsoon, which brings in the cold China Coastal Current water into the Taiwan Strait, where it meets the warm Kuroshio Branch Current coming from the south, is known to form some significant waves. The Taiwan Strait is only about a hundred meters deep—shallow enough that during ice ages and the time of glaciers the island of Taiwan was physically connected to the Chinese mainland; but even in the modern era the 200-mile-long passage—which varies in width from about 100 nautical miles down to just 70 nautical miles and is one of the most vital shipping routes in the world—is known for frequent storms, large swells, and blinding fog and is bedeviled by annual summer typhoons from roughly May to October. Between the typhoons in the summer and the stormy high-wave winter season, there is no predictably perfect and easy time to launch a large-scale amphibious invasion of Taiwan, especially with the strait registering about 150 days a year of winds above 20 knots, rough seas for amphibious ships and landing craft. Any landing on Taiwan’s windy, shallow, and rocky beaches during that time is fraught and risky. Which is why, in the end, China decided to forego a beach landing and attempt an air assault on the island’s port and airfield facilities, the seizure of which would allow for rapid arrival of follow-on troops and logistical supplies to facilitate a successful occupation.
