What type of disturbance does Effects of Hurricane Matthew in Haiti and have in common?
Effects of Hurricane Matthew in Haiti Hurricane Matthew struck southwestern Haiti near Les Anglais on October 4, 2016, leaving widespread damage in the impoverished nation. Matthew was a late-season Category 5 hurricane on the Saffir–Simpson scale, having formed in the southeastern Caribbean on September 28. The hurricane weakened to Category 4 before making landfall near Les Anglais on October 4, at which time the National Hurricane Center estimated maximum sustained winds of 240 km/h (150 mph). This made it the strongest storm to hit the nation since Hurricane Cleo in 1964, and the third strongest Haitian landfall on record. Hurricane-force winds – 74 mph or greater – affected about 1.125 million people in the country. The Haitian government assessed the death toll at 546, although other sources reported more than three times that figure.
Hurricane Catarina Hurricane Catarina (] ) was an extremely rare South Atlantic tropical cyclone that hit southeastern Brazil in late March 2004. The storm developed out of a stationary cold-core upper-level trough on March 12. Almost a week later, on March 19, a disturbance developed along the trough and traveled towards the east-southeast until March 22 when a ridge stopped the forward motion of the disturbance. The disturbance was in an unusually favorable environment with a little bit below-average wind shear and above-average sea surface temperatures. The combination of the two led to a slow transition from an extratropical cyclone to a subtropical cyclone by March 24. The storm continued to obtain tropical characteristics and became a tropical storm the next day while the winds steadily increased. The storm attained wind speeds of 75 mph (120 km/h)—equivalent to a low-end Category 1 hurricane on the Saffir–Simpson scale—on March 26. At this time it was unofficially named "Catarina" and was also the first hurricane-intensity tropical cyclone ever recorded in the Southern Atlantic Ocean. Unusually favorable conditions persisted and Catarina continued to intensify and was estimated to have peaked with winds of 100 mph (155 km/h) on March 28. The center of the storm made landfall later that day at the time between the cities of Passo de Torres and Balneário Gaivota, Santa Catarina. Catarina rapidly weakened upon landfall and dissipated the next day.
