Introduction: Forecasting Super Typhoons (02:10)

FREE PREVIEW

Tokyo was flooded by torrential downpours in July 2017. Typhoon Noru developed rapidly and erratically. Climate change complicates forecasting; scientists innovate meteorological technologies in response.

Unpredictable Systems (04:32)

Hurricane Harvey created record rainfalls and $175 billion in damage. Typhoon Chaba damaged Kume Island buildings and infrastructure. Storm prediction has become difficult, higher ocean surface temperatures intensify development, and residents sometimes do not receive adequate warning.

Growing Prediction Discrepancies (04:03)

As global warming worsens, Japan is more susceptible to super typhoons. Prof. Kosuke Ito creates a computer simulation of storm development, revealing megastorms hitting Okinawa. Data analysis of forecast disparity over 26 years shows increasingly inaccurate projections.

Typhoon Simulation (08:05)

Scientists demonstrate a super typhoon hitting Tokyo. Torrential rainfalls overflow Arakawa River 15 hours before landfall. Officials issue evacuation advisory too late; hospitals unsuccessfully attempt to transfer patients. Storm surges flood the city, stranding thousands for a week.

Advancing Technologies (08:08)

Aircraft helps scientists study the internal processes of typhoons; researchers use Dropsondes to record and transmit data. NASA launched Cygnus in 2016 to measure ocean surface winds. Phased Array utilizes radar to three dimensionally observe cloud movements.

Limited Information Consequences (08:57)

In 2017, rainfall, flood, and landslides killed 37 people on Kyushu Island. Hiromu Seko studies data discrepancies of meteorological predictions. Estimated values for ocean weather are no longer adequate; warming seas create vapors, forming cumulonimbus clouds, and erratic rainstorms.

Predicting Future Storms (08:30)

Himawari-8, launched in 2015, transmits large amounts of data, allowing real time cloud study. The Weather Company innovated artificial intelligence, utilizing global forecast models from 30 years and increasing projection accuracy by 30%..

Extreme Weather Preparation (02:53)

Edogawa Ward is at flood risk during heavy rainfalls. Local governments promote community awareness, educating residents on superstorm unpredictability. Global warming promises to increase the frequency and severity of storms.

Description

Meteorologists around the world are concerned that accurate forecasting is becoming more and more difficult. The biggest reason for this is the rapid increase in the temperature of seawater triggered by global warming. This rise in temperature causes the flow of water vapor and winds to change, thereby allowing super typhoons to expand and increase in number. The accumulated data and the experiences at present are limited. The margin of error in forecasts for heavy rain and typhoons could end up making the resulting damage much worse. This episode introduces new scientific methods and technologies at the frontline of weather forecasting that could save lives.
