Cyclone Favio was the first known tropical cyclone that passed south of Madagascar to strike Africa as an intense tropical cyclone.〔 Early on February 11, 2007, a zone of disturbed weather formed east of Madagascar. Four days later, Favio was named as intensified to a moderate tropical storm while moving southwest. On February 18, the storm was upgraded into a severe tropical storm. Then, it turned west in the general direction of Mozambique. Continuing to intensify, Favio was upgraded to a tropical cyclone early on February 19. Subsequently, the storm began to undergo rapid deepening; the small storm reached intense tropical cyclone status the next day before peaking in intensity. However, the cyclone had weakened somewhat prior to making landfall on February 22 in the Inhambane Province in Mozambique. It rapidly weakened over land and dissipated the next day. While strengthening, Favio brought heavy rains to southern Madagascar. After making landfall, Intense Tropical Cyclone Favio brought widespread damage to Vilanculos in Mozambique, where the cyclone killed four people and injured at least 70 in the town. About 80% of the town was destroyed. Overall, a total of ten people were killed by the storm and nearly 100 others were injured, and combined with an earlier flood, the storm caused $71 million (2007 USD) in damage. Around 130,000 homes suffered damage and 130 schools were leveled by the tropical cyclone. Across the nation, a total of 33,000 people were left homeless during the system. Cyclone Favio destroyed of crops. In Zimbabwe, 400 electricity poles were downed. During the aftermath of the storm, a number of agencies provided assistance to victims of Cyclone Favio in Mozambique. One agency donated $626,500, helping transport 50,000 mosquito nets to the devastated area. A total of 5,500 bars of soap, 1,600 buckets, 50 baths, and over 180 latrines were distributed to the victims of the devastated area. In all, the government was praised for how well they handled the disaster. ==Meteorological history== Cyclone Favio originated from a zone of disturbed weather that was first classified by the Météo-France office on Réunion (MFR) at 1200 UTC February 11, 2007.〔(【引用サイトリンク】url=http://www.meteo.fr/temps/domtom/La_Reunion/TGPR/saison20062007/09_table.html )〕 Twelve hours later, the Joint Typhoon Warning Center (JTWC) issued their first advisory on the system. Midday on February 12, MFR upgraded the system into a tropical disturbance and noted that its rating at that time on the Dvorak technique was 2.0.〔 According to the JTWC, an area of convection developed south-southwest of Diego Garcia.〔 Initially, however, the convection was not very concentrated near the center. However, sea surface temperatures in the area were somewhat warm so gradual intensification was predicted and the storm was projected to become a severe tropical storm within 48 hours. Situated in an environment of low wind shear and good outflow, thunderstorm activity soon increased and thus started to consolidate around the storm's atmospheric circulation. Continuing to encounter more favorable conditions, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) on February 14.〔 Meanwhile, MFR upgraded the system into a tropical depression.〔 Eighteen hours later, the system was named ''Favio'' by the Meteorological Services of Mauritius〔 as the system; according to MFR, had intensified into a moderate tropical storm.〔 Moving very steadily southwest,〔 the storm gradually intensified.〔 Early on February 15, the JTWC announced that that system had intensified into a tropical storm. After intensifying slightly (based on JTWC data) that evening, the storm briefly weakened overnight, only to re-intensify the next morning.〔 On February 16, Favio turned southwest in response to a large subtropical ridge.〔 Despite low wind shear, Favio remained a moderate tropical storm for several days; however, on February 18, MFR announced that Favio had intensified into a severe tropical storm.〔 Subsequently, the storm turned west as the ridge merged with another one centered over South Africa.〔 Two days later, the agency then upgraded the system into cyclone status.〔 At 0000 UTC that day, on February 19, the JTWC upgraded the system into a Category 1 hurricane-equivalent on the Saffir-Simpson Hurricane Wind Scale (SSHWS)〔 though not much additional intensification was predicted. Upon becoming a hurricane, thunderstorm activity began to develop around an eye. Favio turned west-northwest, traversing the Mozambique Channel while beginning to deepen.〔 At 0000 UTC February 20, the JTWC declared that Favio had intensified into a Category 2 hurricane-equivalent on the SSHWS.〔 Several hours later, Favio was then upgraded into an intense tropical cyclone by MFR〔 as the system developed a very small eye. Simultaneously, Cyclone Favio was upgraded into a Category 3 hurricane on the SSHWS via the JTWC. During the afternoon hours of February 20, the JTWC reported that Favio had developed winds equivalent to Category 4 intensity.〔 That evening, MFR noted that Cyclone Favio had peaked in intensity, with winds of ,〔 becoming the most intense tropical cyclone south of the 25th parallel over the Mozambique Channel since the satellite era began. Six hours later, the JTWC announced that Favio had peaked in intensity, with winds. This made Favio equal to a mid-level Category 4 hurricane.〔 At the time of its peak, Favio had developed a well-defined eye. Shortly after its peak, Cyclone Favio began to weaken;〔 the core of the storm started to become disrupted on the northwestern quadrant. The JTWC expected Favio to continue to weaken, and dissipate within 48 hours over land. The eye disappeared off of satellite imagery, though by early February 22, this feature had re-developed. That afternoon, the storm was estimated to have made landfall in southern Mozambique. At that time, the JTWC reported winds of , a Category 1 system on the SSHWS.〔 On the other hand, MFR estimated winds of (an intense tropical cyclone).〔 Upon making landfall, it did so on the seventh anniversary of the last intense tropical cyclone, Eline, to strike Mozambique. Favio was also the first tropical cyclone to hit the country since Cyclone Japhet did during the 2002-03 South-West Indian Ocean cyclone season.〔 By early February 23, winds had dropped below hurricane-force according to the JTWC, while the storm dissipated later that day.〔 Around that time, MFR stopped monitoring the system as well.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cyclone Favio」の詳細全文を読む スポンサード リンク
