Typhoon Hinnamnor (2022)
Typhoon Hinnamnor, known in the Philippines as Super Typhoon Henry, was a very large and powerful tropical cyclone that impacted Japan and South Korea. The eleventh named storm, fourth typhoon, and the first super typhoon of the 2022 Pacific typhoon season, Hinnamnor originated from a disturbed area of weather first noted on August 27 by the JTWC. This area soon formed into ''Tropical Storm Hinnamnor'' on the next day. The storm rapidly intensified, and became a typhoon on the August 29. Overnight, Hinnamnor cleared a small eye along with a well-defined CDO, and intensified into a Category 5-equivalent super typhoon, the first tropical cyclone to do so in 2022. Hinnanmor then weakened due to undergoing an eyewall replacement cycle. However, it re-intensified to a Category 5 super typhoon with a larger eye and CDO south of Okinawa. An increasingly hostile environment caused it to lose its convective features the night of September 1, weakening it down to a Catego ...

Taiwan
Taiwan, officially the Republic of China (ROC), is a country in East Asia, at the junction of the East and South China Seas in the northwestern Pacific Ocean, with the People's Republic of China (PRC) to the northwest, Japan to the northeast, and the Philippines to the south. The territories controlled by the ROC consist of 168 islands, with a combined area of . The main island of Taiwan, also known as ''Formosa'', has an area of , with mountain ranges dominating the eastern two-thirds and plains in the western third, where its highly urbanised population is concentrated. The capital, Taipei, forms along with New Taipei City and Keelung the largest metropolitan area of Taiwan. Other major cities include Taoyuan, Taichung, Tainan, and Kaohsiung. With around 23.9 million inhabitants, Taiwan is among the most densely populated countries in the world. Taiwan has been settled for at least 25,000 years.

Philippine Standard Time
Philippine Standard Time (PST or PhST; fil, Pamantayang Oras ng Pilipinas), also known as Philippine Time (PHT), is the official name for the time zone used in the Philippines. The country only uses one time zone, at an offset of UTC+08:00, but has used daylight saving time for brief periods in the 20th century. Geographic details Geographically, the Philippines lies and 126°34′ east of the Prime Meridian, and is physically located within the UTC+08:00 time zone. Philippine Standard Time is maintained by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA). The Philippines shares the same time zone with China, Taiwan, Hong Kong, Macau, Malaysia, Singapore, Western Australia, Brunei, Irkutsk, Central Indonesia, and most of Mongolia. History Philippine Standard Time was instituted through Batas Pambansa Blg. 8 (that defined the metric system), approved on December 2, 1978, and implemented on January 1, 1983. The Philippines is one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

East China Sea
The East China Sea is an arm of the Western Pacific Ocean, located directly offshore from East China. It covers an area of roughly . The sea’s northern extension between mainland China and the Korean Peninsula is the Yellow Sea, separated by an imaginary line between the eastern tip of Qidong at the Yangtze River estuary and the southwestern tip of South Korea's Jeju Island. The East China Sea is bounded in the east and southeast by the middle portion of the first island chain off the eastern Eurasian continental mainland, including the Japanese island of Kyushu and the Ryukyu Islands, and in the south by the island of Taiwan. It connects with the Sea of Japan in the northeast through the Korea Strait, the South China Sea in the southwest via the Taiwan Strait, and the Philippine Sea in the southeast via gaps between the various Ryukyu Islands (e.g. Tokara Strait and Miyako Strait). Most of the East China Sea is shallow, with almost three-fourths of it being less than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ryukyu Islands
The , also known as the or the , are a chain of Japanese islands that stretch southwest from Kyushu to Taiwan: the Ōsumi, Tokara, Amami, Okinawa, and Sakishima Islands (further divided into the Miyako and Yaeyama Islands), with Yonaguni the westernmost. The larger are mostly high islands and the smaller mostly coral. The largest is Okinawa Island. The climate of the islands ranges from humid subtropical climate (Köppen climate classification ''Cfa'') in the north to tropical rainforest climate (Köppen climate classification ''Af'') in the south. Precipitation is very high and is affected by the rainy season and typhoons. Except the outlying Daitō Islands, the island chain has two major geologic boundaries, the Tokara Strait (between the Tokara and Amami Islands) and the Kerama Gap (between the Okinawa and Miyako Islands). The islands beyond the Tokara Strait are characterized by their coral reefs. The Ōsumi and Tokara Islands, the northernmost of the islands, fall un ...

Philippine Area Of Responsibility
The Philippine Area of Responsibility (PAR) is an area in the Northwestern Pacific where PAGASA, the Philippines' national meteorological agency, monitors weather occurrences. Significant weather disturbances, specifically tropical cyclones that enter or develop in the PAR, are given Philippine-specific names. Boundary The area is bounded by six points namely: * * * * * * This area encompasses almost all of the land territory of the Philippines, except for the southernmost portions of the province of Tawi-Tawi, and some of the country's claimed islands in the Spratly Islands, Spratlys.

Eye (cyclone)
The eye is a region of mostly calm weather at the center of tropical cyclones. The eye of a storm is a roughly circular area, typically in diameter. It is surrounded by the ''eyewall'', a ring of towering thunderstorms where the most severe weather and highest winds occur. The cyclone's lowest barometric pressure occurs in the eye and can be as much as 15 percent lower than the pressure outside the storm. In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall. In weaker tropical cyclones, the eye is less well defined and can be covered by the central dense overcast, an area of high, thick clouds that show up brightly on satellite imagery. Weaker or disorganized storms may also feature an eyewall that does not completely encircle the eye or have an eye that features heavy rain. In all storms, however, the eye is the location of the storm's minimum barometric pressure—where the atmospheric pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microwave Imaging
Microwave imaging is a science which has been evolved from older detecting/locating techniques (e.g., radar) in order to evaluate hidden or embedded objects in a structure (or media) using electromagnetic (EM) waves in microwave regime (i.e., ~300 MHz-300 GHz). Engineering and application oriented microwave imaging for non-destructive testing is called microwave testing, see below. Microwave imaging techniques can be classified as either quantitative or qualitative. Quantitative imaging techniques (are also known as inverse scattering methods) give the electrical (i.e., electrical and magnetic property distribution) and geometrical parameters (i.e., shape, size and location) of an imaged object by solving a nonlinear inverse problem. The nonlinear inverse problem is converted into a linear inverse problem (i.e., Ax=b where A and b are known and x (or image) is unknown) by using Born or distorted Born approximations. Despite the fact that direct matrix inversion methods ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Central Dense Overcast
The central dense overcast, or CDO, of a tropical cyclone or strong subtropical cyclone is the large central area of thunderstorms surrounding its circulation center, caused by the formation of its eyewall. It can be round, angular, oval, or irregular in shape. This feature shows up in tropical cyclones of tropical storm or hurricane strength. How far the center is embedded within the CDO, and the temperature difference between the cloud tops within the CDO and the cyclone's eye, can help determine a tropical cyclone's intensity with the Dvorak technique. Locating the center within the CDO can be a problem with strong tropical storms and minimal hurricanes as its location can be obscured by the CDO's high cloud canopy. This center location problem can be resolved through the use of microwave satellite imagery. After a cyclone strengthens to around hurricane intensity, an eye appears at the center of the CDO, defining its center of low pressure and its cyclonic wind field. Tropic ...
