A Chinese Culture University (CCU) professor last month launched a rainbow forecasting system aimed at helping tourists, meteorologists and photographers know when and where to find rainbows.
Atmospheric science professor Chou Kun-hsuan (周昆炫) said earlier this week that the “Rainbow Weather Index” is based on data from the Central Weather Bureau and the university, such as precipitation, wind speed, wind direction and humidity.
After months of adjustments, Chou launched the system and said it is now 85 percent accurate in predicting a rainbow.

“We hope the service, which is only available for this region, can attract more people to look for rainbows on our campus,” Chou said.
He created the index after he, his colleagues and students documented a rainbow in Taipei’s Yangmingshan (陽明山) that lasted almost nine hours in 2017, and was last year recognized by Guinness World Records as the longest rainbow recorded, he said.
Chou analyzed the weather conditions between Nov. 1 last year and Jan. 31, and found that a rainbow appeared on 23 of those days, which he used to establish the forecasting system in June, he said.
The index was designed to reflect high, medium and low probabilities of a rainbow occurring, with a 74 percent or higher chance considered high, 63-74 percent considered medium and 63 percent or lower deemed low, Chou said.
In “high” probability scenarios, significant northeasterly winds provide sufficient moisture, accompanied with sunlight that is sufficient to keep the rainbow bright, he said.
Between Oct. 29 and Sunday last week, forecasts and actual conditions matched 29 days for a rainbow to occur.
“We have the right formula here in Yangmingshan,” Chou said, adding that compared with rainbows that appear following summer afternoon thunderstorms, rainbows generated by seasonal winds in winter last longer.
One-third of Taiwan’s rainbows each year occur between November and January, which Chou calls the “hot season.”
Rainbow chasers could start on Wednesday, when according to the index, there is an 87.05 percent chance of seeing a rainbow.
‘UNAFRAID’: Most Taiwanese do not seem to be aware of the danger of war and might be unprepared, a KMT legislator said of the poll by an affiliated foundation Nearly 60 percent of Taiwanese believe that a war between Taiwan and China is “unlikely” or “impossible,” a survey released yesterday by the National Policy Foundation showed. The survey asked participants if they thought there was a possibility of war between the two sides of the Taiwan Strait based on recent developments, said the foundation, which is affiliated with the Chinese Nationalist Party (KMT). While 42.5 percent of respondents thought it was “unlikely” and 17.1 percent believed it was “impossible,” 5.1 percent said it was “very likely” and 17.2 percent said it was “fairly possible,” the survey showed. Another 18.2 percent gave
The Kaohsiung Prosecutors’ Office on Monday indicted a Chinese sea captain over his alleged involvement in the killing of four pirates at sea in 2012, while serving as the captain of a Taiwanese fishing vessel. The suspect, identified by the media as 43-year-old Wang Fengyu (汪峰裕), was charged with homicide and breaches of the Controlling Guns, Ammunition and Knives Act (槍砲彈藥刀械管制條例), the indictment read. Wang asked two Pakistani mercenaries that he hired as acting captain of the Kaohsiung-registered Ping Shin No. 101 to fire on and kill four suspected Somalian pirates in the Indian Ocean off the Somalian coast on Sept. 29,
UPGRADE: The system is more efficient than others, which typically involve longer procedures that can produce pseudo-positive or pseudo-negative results The National Synchrotron Radiation Research Center yesterday unveiled an infrared wax physisorption kinetics imaging system, which it said efficiently detects 10 types of cancer. Through scanning tissue section samples, the imaging system can detect colon, breast, stomach, oral, ovarian, cervical, prostate and skin cancer, as well as neuroendocrine tumors and glioblastoma, center associate research fellow Lee Yao-chang (李耀昌) told a news conference in Taipei. The system uses paraffin and beeswax with organic solutions as developers for its infrared imaging device, which can mark abnormal polysaccharides on the surface of cancer cells in six to 15 minutes, while the wax is absorbed by
China is trying to convince Taiwanese that an authoritarian system is preferable to democracy, the Information Operations Research Group (IORG) said at a conference yesterday. China has been employing Taiwanese sympathetic to its “united front” tactics to help spread disinformation about democracy and Taiwanese society through social media, television programs, YouTube and by other means, the group said at the conference to promote public awareness of China’s cognitive warfare campaign. In the group’s latest report, it highlighted eight disinformation discussions that its researchers listed under three main topics: flu viruses in the US are deadlier than COVID-19; US troop movements caused the
