They typically form when the sea-surface temperature is above 26.5°C. One of them is the tropical cyclone “FUNSO”. Only a small percentage (3%) of this released energy is converted into Kinetic energy to maintain cyclone … It started as a low pressure at around 15 0S of equator just off the coast of Mozambique along the Mozambique Channel. Funso reached the equivalent of a Category 4 hurricane on January 25, … The term "cyclone" refers to their cyclonic nature, with wind Further intensification was forecast to be limited by the cyclone's interaction with the coast of Mozambique, as well as upwelling from its slow movement. At the time, the storm was located about 110 km (70 mi) east of Quelimane, Mozambique,[15] and its movement was nearly stationary. Intense Tropical Cyclone Funso was a powerful tropical cyclone which produced flooding in Mozambique and Malawi in January 2012. Tropical Cyclone Funso is now a dangerous Category 4 cyclone in the Mozambique Channel, moving southward between Mozambique on the African mainland and the island nation of Madagascar. what is tropical cyclone ? As Funso became a major cyclone two NASA satellites were providing forecasters with valuable storm information. An average tropical cyclone can travel about 300 to 400 miles a day, or about 3,000 miles before it dies out. Therefore, a tropical cyclone can be thought of as Once forecasters have determined that a tropical cyclone is likely to make landfall, … [2] Late on January 18, the Joint Typhoon Warning Center (JTWC) issued a tropical cyclone formation alert, indicating a high chance of the system becoming a tropical cyclone. [7] Funso rapidly intensified after the eye became better established, and the MF upgraded the storm to a tropical cyclone – the equivalent of a 120 km/h (75 mph) hurricane – early on January 20. Tropical cyclone is defined as a non-frontal, synoptic-scale cyclone developing over tropical and sub-tropical waters at any level and having a definitely organized circulation. [11], On January 20, Funso turned to the west and slowed, due to its position between a ridge to the northwest of Madagascar and another ridge near the Mozambique–South Africa border. Torrential rainfall results in flash-flooding, flooding, and potential landslides and mudslides. Tropical Cyclone Funso is now a dangerous Category 4 cyclone in the Mozambique Channel, moving southward between Mozambique on the African mainland and the island nation of Madagascar. The winds are driven by this low-pressure core and by the rotation of Earth, which deflects the path of the wind through a phenomenon known as the Coriolis force. A “Tropical Disturbance is a persistent thunderstorm regi… Real-time measurements are usually taken in the periphery of the cyclone, where conditions are less catastrophic and its true strength cannot be evaluated. A number of the paths are erratic. %�쏢 Computer models currently do well in forecasting the path of tropical cyclones, but they are not as reliable in forecasting changes in intensity more than 24 hours in advance. [24] At the same time, the JTWC estimated the cyclone intensified further to peak 1 minute sustained winds of 220 km/h (140 mph), based on estimates via the Dvorak technique. Paths of other cyclones can be seen on the following Wikipedia pages: 1988-89 SW Indian Ocean Cyclone Season. Funso underwent another eyewall replacement cycle on January 27 as it started weakening. A building ridge to the north forced the cyclone to the southeast into an area favorable for re-intensification. <> Tropical cyclone track forecasting involves predicting where a tropical cyclone is going to track over the next five days, every 6 to 12 hours. For this reason, there are teams ofmeteorologists that move into the path of tropical cyclones to help evaluate their strength at the point oflandfall. These will be respectively yellow, orange, pink, red and violet. 5 0 obj It was the eighth tropical cyclone, the sixth named storm and the second tropical cyclone to form during the 2011–12 South-West Indian Ocean cyclone season. a tropical cyclone is an intense low pressure area or a whirl in the atmosphere over tropical and sub-tropical waters • with organised convection i.e. [33], In Nicoadala District, the storm destroyed 66 houses and killed two people. Nevertheless, some local tourists voluntarily evacuated the coastal city of Inhambane in Mozambique in anticipation of the storm. [23] MF remarked that Funso weakened below intense tropical cyclone intensity early on January 25. Tropical cyclones can continue for many days, even weeks, and may follow quite erratic paths. e�|���Z��T��(o�'�V�D%��?�x��l�|��D�&3�����炙y�n���?^�w������O*�Y>��?�����7ߺ;�����B�b�&�dp��s�N�޽������ſ��T� ��^�)Ї\wz�|o&�T�7��Sڟ���r���@S��4[�����^M��Y���=�u&`B){zG�Y�'g?���$����f���:==ߋI�g ��>���0΢B���e�! Tropical Cyclone can be compared to a heat engine. Funso was also the first intense tropical cyclone since Gelane in 2010 and the first storm to affect Mozambique since Jokwe in 2008. The energy input is from warm water and humid air over tropical oceans. [3] At 0000 UTC the next day, Météo-France (MF) classified it as Tropical Disturbance 8 about halfway between Mozambique and Madagascar in the northern Mozambique Channel. [31], Initial forecasts suggested that the cyclone would impact South Africa[37] or make landfall in southern Mozambique, but this became less likely as the storm continued tracking south. (��5� [36] The cyclone hit the country about a week after Subtropical Depression Dando struck southern Mozambique, causing flooding and deaths. Release of heat is through condensation of water vapour to water droplets/rain. Tropical Cyclone Funso lingers over the Mozambique Channel in this natural-color image from January 25, 2012. Tropical Cyclone Funso is now a dangerous Category 4 cyclone in the Mozambique Channel, moving southward between Mozambique on the African mainland and the island nation of Madagascar. Tropical cyclones which occur in the Atlantic region usually comprise less than 15% of global tropical cyclone … As Funso became a major cyclone two NASA satellites were providing forecasters with valuable storm information.Two instruments aboard NASA's Aqua satellite and instruments aboard NASA and JAXA's During the 2011-2012 the south-west Indian Ocean got hit by several tropical disturbance and tropical cyclone. [36] Traffic re-opened by January 24. [40] Across Southern Malawi, the storm destroyed more than 320 houses and flooded 125 more, primarily in Bangula and Phokela. [34] In Chokwe, at least 3,900 hectares of rice fields[32] were flooded, while three people were missing in Guijá District, Gaza Province on January 25. Funso was also the first intense tropical cyclone since Gelane in 2010 and the first storm to affect Mozambique since Jokwe in 2008. [22] Late on January 24, the cyclone began an eyewall replacement cycle, which initiated a brief weakening trend. Tropical Cyclone Funso is now a dangerous Category 4 cyclone in the Mozambique Channel, moving southward between Mozambique on the African mainland and the island nation of Madagascar. [45][46] Meteorologists predicted the flooding rains to continue for most of Mozambique throughout the first months of 2012. According to the definition of the World Meteorological Organization (WMO), tropical cyclones are “atmospheric disturbances of a few hundred kilometres wide scale, originating over tropical or sub-tropical waters and presenting an organized thunderstorm activity and acycloniccirculation, more intense at the surface than at altitude“. [16] As the storm moved away from the Mozambique coastline, the convection became better organized,[17] and the eye gradually reformed. Veل�����7��\-�$.;+����<9gh��y���7�4�:%3��>�ė��6�w�#��=��sje�s��>�T. [31], In Mozambique, flooding from the tropical cyclones cut off the arterial North-South Highway to Maputo, the capital of the country, as the Komati River flooded its banks. The color green will represent normal (safe) weather conditions. [28], Although the core of the storm never made landfall in Mozambique, over three million people there were affected by tropical storm-force winds. [5] Though the system's low-level structure was disorganized, it gradually improved over the course of the day;[6] MF upgraded the system to Moderate Tropical Storm Funso at 1200 UTC on January 19, or about 12 hours after its formation. The combination of wind-driven waves and the low-pressure of a tropical cyclone can produce a coastal storm surge – a huge volume of water driven ashore at high speed and with immense force that can wash away structures in its path and cause significant damage to the coastal environment. At least 70,000 people were without a clean drinking water supply following the storm, and more than 56,000 were left homeless in Mozambique. Tropical cyclones are low pressure systems that form over warm tropical waters. A catalog of NASA images and animations of … [35] After affecting the central Mozambique provinces, Funso brushed the coastline of the Inhambane Province in the south with rains and winds of 70 km/h (40 mph). or more. It was the eighth tropical cyclone, the sixth named storm and the second tropical cyclone to form during the 2011–12 South-West Indian Ocean cyclone season. [41][42] At least 30 villages became isolated after flooding destroyed roads and bridges between Blantyre and Nsanje. Flooding also occurred in Inhambane Province. This can be used to help track and predict the path of a tropical cyclone. [32] High water levels occurred on the Movene River, an upstream tributary of the Umbeluzi River from which Maputo gets its water supply, which limited access to the treatment plant, leaving the city's water polluted. The terms "hurricane" and "typhoon" are regionally specific names for a strong "tropical cyclone".A tropical cyclone is the generic term for a non-frontal synoptic scale low-pressure system over tropical or sub-tropical waters with organized convection (i.e. When autocomplete results are available use up and down arrows to review and enter to select. In the Pacific, there have been a number of intense tropical cyclones that have resulted in significant loss and damage for island states in recent years. thunderstorm activity • winds at low levels, circulating anti-clockwise in the northern hemisphere and clockwise in the southern hemisphere • pressure increases outwards from the centre of a cyclonic storm. [19] Late on January 23, the JTWC estimated 1 minute sustained winds of 215 km/h (135 mph), and the agency forecast further strengthening to 260 km/h (160 mph). Forecasters in Mozambique kept a wary eye on Tropical Cyclone Funso as it made its way down an already drenched coast this week. (Non-severe) tropical cyclone, tropical storm (winds >= 34 knots, < 64 knots) Tropical cyclone is generic term for Tropical … The agency noted that the eyewall replacement cycle finished and produced a well-defined eye 28 km (17 mi) in diameter. The following picture, from Wikipedia, shows the paths of the cyclone tracks for the 1988-89 south west Indian Ocean cyclone season. II.2 Outline of the Tropical Cyclone Early Warning System A five-phase Tropical Cyclone Warning System is used by the MDC and each phase is represented by a specific color. At least 15 passengers drowned while dozens remain missing. Around that time, there was a warm spot, or a precursor to an eye, in the middle of a circular area of convection. For this reason, there are teams of meteorologists that move into the path of tropical cyclones to help evaluate their strength at the point of landfall. [13] Despite land interaction, Funso intensified further, and the JTWC assessed 1 minute winds of 185 km/h (115 mph) early on January 21, based on the appearance of a well-defined eye 15 km (9 mi) in diameter. These phenomena have different names depending on their intensity, measured by the strength of the surface wind. [14] Around the same time, MF estimated the storm attained 10 minute maximum sustained winds of 165 km/h (105 mph), making Funso an intense tropical cyclone. Tropical cyclones are compact, circular storms, generally some 320 km (200 miles) in diameter, whose winds swirl around a central region of low atmospheric pressure.

Anatomy of a cyclone. [12] The convection to storm's west over land diminished while the center remained well-organized. "Twenty five people died in the last two weeks as a result of the Cyclones 'Dando' and 'Funso, the highest number of deaths was reported in Zambezia with a total of 16 victims, followed by … During the overnight hours of January 18, a ship carrying 54 people sank on its way from Anjouan to Mayotte amidst rough seas produced by Funso, while the developing storm remained offshore in its early stages. Major Tropical Cyclone Funso analyzed by 2 NASA satellites January 25, 2012 Tropical Cyclone Funso is now a dangerous Category 4 cyclone in the Mozambique Channel, moving southward between Mozambique on the African mainland and the island nation of Madagascar. The flooding also killed livestock and affected maize fields,[39] leaving whole communities at risk of starvation. As Funso became a major cyclone two NASA satellites were providing forecasters with … stream Tropical Cyclone Funso A catalog of NASA images and animations of our home planet These winds tend to reverse the direction of the tropical cyclone to an eastward path. [6], Upon forming on January 19, the depression was moving to the southwest along the northern edge of a ridge. Overall, more than 5000 people were displaced by the weather conditions. MAPUTO, Jan 25, 2012 (From AFP) - At least 25 people have been killed as a result of two tropical cyclones that hit central and southern Mozambique over the past two weeks, government officials said on Wednesday. Tropical Cyclone Funso lingers over the Mozambique Channel in this natural-color image from January 25, 2012. Reinforced aircraft, fitted with various scientific instruments, fly through and over tropical cyclones to collect data. The history of tropical cyclone track forecasting has evolved from a single-station approach to a comprehensive approach which uses a variety of meteorological tools and methods to make predictions. %PDF-1.4 Cyclone Funso posed no imminent threat to the northeastern coast of South Africa. [32], The impact of Cyclone Funso stalling over Zambezia Province worsened an ongoing flood situation that had been exacerbated by monsoon rains, producing flooding in Mozambique, Malawi, South Africa and Swaziland. Intense Tropical Cyclone Funso was a powerful tropical cyclone which produced flooding in Mozambique and Malawi in January 2012. A cyclone will dissipate once it … In Fiji, over 60% of the population was affected with 22% of the [31] Seven of the fatalities occurred in the Maganja da Costa District, where 1,610 houses were destroyed,[32] and one death was in Zambezia's capital city of Quelimane, where heavy rainfall flooded most neighborhoods, owing to poor drainage systems.
