To determine just how strong the Kujira Tropical Storm is, NASA decided to analyze the cloud top temperatures. It chose to use infrared light in this case. According to the imagery, there were two strong spots. They are the storm’s center and a thunderstorms’ band on the west side of the Kujira Tropical storm.
In the beginning, the storm was just but a low-pressure area. However, by 5 p.m. EDT of September 26, an increase in consolidation and strength saw it change into a tropical depression. Then, the depression has strengthened into a tropical storm by 11 a.m. EDT of September 27. That’s also when the tropical storm got the name Kujira.
NASA chose the infrared light to identify the temperature of the storm. Using the infrared data, it was able to relay the cloud top temperatures. They are a significant determinant of the strength of any particular storm. The colder the cloud top temperatures, the stronger the storm. Equally important, strong storms tend to extend into the troposphere more than their weak counterparts.
Thanks to the data, NASA identified the strength of the storm and the strongest points. Its Aqua satellite used the MODIS (Moderate Resolution Imaging Spectroradiometer) equipment. The temperatures recorded for the strong spots were between -80 and -70 degrees Fahrenheit, equivalent to -62.22 degrees Celsius to -56.6 degrees Celsius. According to the experts, the low temperatures indicated not only intense storms but also a possibility of heavy rain.
As of 11 a.m. EDT of September 28, the Tropical Storm Kujira’s center was at a latitude and longitude of 29.7 degrees N and 153.3 degrees E, respectively. Therefore, the distance between the storm and Minami Tori Shima is approximately 286 nautical miles. The isolated Japanese coral atoll is around 1148 miles equivalent to 1848 kilometers from the southeastern side of Tokyo, Japan.
The storms’ winds are at a speed of 45 knots, which is 52 m per hour or 83 km per hour. High gusts also characterize this Kujira storm. It is moving toward the north, and its course is the open waters of the Pacific Ocean, precisely the north-western side.
According to the forecast, the intensity will increase because it will interact with the elongated area of high pressure known as the subtropical ridge. The power will also increase further upon coming into contact with the mid-latitude westerlies’ winds. That could see it commence its extratropical transition. On the other hand, its encounter with the increased vertical wind may make the tropical storm weaken and tear apart.
