Situated between 37° north and 34° south, Africa mainly lies within tropics. Only the northern and southern tips have a Mediterranean climate. Africa is therefore a predominantly warm continent. The mean annual temperature is above 20°C throughout the tropics, and annual daily temperatures are only higher in the desert. The rains determine the climate. The equatorial climate extends over the Congo Basin, on either side of the equator. Temperatures are high and vary only slightly over the year (25°C on average). There is regular rainfall, totalling in excess of 1,500 mm, and sometimes as much as 2,000 mm.
The tropical climate is characterized by alternating dry and rainy season. The difference between the seasons becomes more marked the nearer o the tropics; similarly, there is a greater variation in temperatures and total rainfall decreases. Due to the size of the continent, the influence of latitude predominant in the northern hemisphere; there is a series of tropical belts parallel to the equator.
The wet tropical climate is similar to the equatorial climate in the c amount of rainfall, but there are two dry seasons of unequal duration (August and December to March in the northern hemisphere). This type of climate prevails along the Gulf of Guinea, from Sierra Leone to Cote d’Ivoire. In the Great lakes region, apart from on high ground, rainfall is less than 1,500 mm per annum. In the dry tropical, or Sudanese, climate, the dry season lasts longer (three to six months on average) the nearer one is to the tropics. The drought is accentuated by the harmattan, a dry, warm wind that blows towards the Atlantic. The wet season, known as the Hivernage, arrives when the sun reaches its zenith. The annual rainfall exceeds 1,000 mm in the south of Mali but remains below 800 mm to the north of Nigeria. The climate in the Sahel is affected by increasingly rare rainfall (less than 500 mm), which only occurs during a short period (three months at the most); there is also extreme irregularity from one year to the next. Temperatures, much higher than in the wet regions, can reach 40°C at the end of the dry season.
South of the equator, the seasons are the reverse of the northern hemisphere and the climate zones run from east to west. Arid and semi-arid zones are confined to the south-west, whereas the coastal strip along the Indian Ocean, to the southeast, has a very wet climate (monsoon). On average, temperatures are lower than in the northern hemisphere. These differences are linked to the proximity of the sea and the relatively high relief in the southern part of the continent. In Madagascar, the eastern side of the island is very wet as it is exposed to trade winds (over 2,000 mm of rainfall per year), as opposed to the western side which is “downwind” and much drier.
The desert region extends unevenly in both tropics. In the north, the Sahara covers over 8 million km2, whereas the Kalahari and the Namib occupy a less extensive area in southern Africa. Rainfall is frequently below 100 mm per year. High atmospheric pressure and cold sea currents result in drought that is accentuated by strong winds. Daily (up to 50°C) and annual (25 to 30°C) temperature variations are high.
A Mediterranean climate is confined to the northern and southern tips of the continent. Summers are warm and dry, winters mild and damp. Temperature deviations are greater inland, where frost and snow are frequent. In the Maghreb, the mean annual temperature is 18°C on the plains, but only 14°C in the Atlas Mountains.
Africa is affected by climate change that will have serious consequences on agricultural output and the health of the population (for example, lower and more irregular rainfall encourages greater numbers of disease-bearing insects and makes producing enough to eat yet more challenging).
Nigeria’s meteorology body warns of a dusty and hazy Monday
According to NiMet, hazy conditions are expected to prevail over the central states within the forecast period
The Nigerian Meteorological Agency (NiMet) has predicted dusty haze and hazy conditions over the north and central cities with possibilities of thunderstorms over some parts of the coastal cities on Monday.
NiMet’s Weather Outlook on Sunday in Abuja forecast dusty hazy conditions with localised visibility range between 2 to 5 km over Potiskum, Maiduguri, Katsina, Kano, Damaturu, and Yola during the forecast period. It further predicted day and night temperatures of the region to be between 31 and 36 degree Celsius and between 14 and 19 degree Celsius respectively.
According to NiMet, hazy conditions are expected to prevail over the central states within the forecast period with day and night temperatures of 27 to 37 degree Celsius and 12 to 23 degree Celsius respectively.
For Southern states, partly cloudy to sunny conditions with early morning mist/fog over Calabar, Abeokuta, Ijebu-Ode, Akure, Oshogbo, Ibadan, Ado-Ekiti, Port Harcourt, Eket, Yenagoa, and Warri are envisaged over the region in morning hours.
The meteorological agency envisages the chances of thunderstorms over Port Harcourt, Calabar, and Lagos during the afternoon and evening hours.
It predicted day and night temperatures of the region to be between 31 and 37 degree Celsius and between 20 and 24 degree Celsius respectively.
Floods kill 29 in Kenya
Twenty five out of the country’s forty seven counties, including the capital of Nairobi, have experienced heavy rainfall and are on high alert for flooding.
Those living in flood-prone areas have been advised to vacate their homes and relocate to higher ground.
Twenty-nine people across several counties have lost their lives and over 12,000 have been displaced across Kenya in recent days as incessant and heavy rains continue to pound the East African nation.
The Kenya Meteorological Department has issued an advisory on the anticipated heavy downpour and warned residents in several regions to be on the lookout for floods. Twenty-five out of the country’s forty-seven counties, including the capital of Nairobi, has experienced heavy rainfall and are on high alert for flooding.
The most adversely affected are the counties of Mandera, Wajir, Marsabit, Kwale, Lamu, Turkana and Garissa. Relief efforts by the Kenya Red Cross, UNICEF and the Kenya Government are underway in various parts of the country.
Camps for displaced families have been set up in the hard-hit counties of Wajir and Mandera where 8000 and 5000 households respectively have been affected by the floods. This initiative, however, has been significantly hampered by impassable, flooded roads and access routes.
The Kenyan government, through its spokesperson, Col. (Rtd) Cyrus Oguna, has stated that in addition to the loss of human life, the sectors of education, roads, agriculture and water have been adversely affected by the floods.
Pay Attention: UN says millions may die of starvation in Somalia’s drought
In the case of the agricultural sector, farmlands in the affected areas have been completely submerged and an estimated 10,000 livestock lost. Those living in flood-prone areas have been advised to vacate their homes and relocate to higher ground.
Deaths in Mozambique and Zimbabwe cyclone have exceeded 300
Mozambique’s government has declared a national emergency and ordered three days of national mourning.
The death toll from a cyclone that smashed into Mozambique and Zimbabwe rose to more than 300 as rescuers raced against the clock to help survivors and the UN led the charge to provide aid.
“We already have more than 200 dead, and nearly 350,000 people are at risk,” Mozambican President Filipe Nyusi announced Tuesday, while the government in Zimbabwe said around 100 people had died but the toll could be three times that figure.
The UN, meanwhile, said that one of the worst storms to hit southern Africa in decades had also unleashed a humanitarian crisis in Malawi, affecting nearly a million people and forcing more than 80,000 from their homes.
Four days after Tropical Cyclone Idai made landfall, emergency teams in central Mozambique fanned out in boats and helicopters, seeking to pluck survivors from roofs and treetops in an inland sea of floodwater, sometimes in the dead of night.
Air force personnel from Mozambique and South Africa were drafted in to fly rescue missions, while an NGO called Rescue South Africa said it had picked up 34 people since Friday night, using three helicopters.
“It is the only way to access the people that are stranded,” Rescue SA’s Abrie Senekal told AFP, saying the NGO was trying to hire more helicopters.
‘Like a tsunami’
Scher, who heads Rescue SA, said the helicopter teams were having to make difficult decisions.
“Sometimes we can only save two out of five, sometimes we drop food and go to someone else who’s in bigger danger,” he said.
“We just save what we can save and the others will perish.”
In Nhamatanda, some 60 kilometres northwest of Beira, 27-year-old Jose Batio and his wife and children survived by climbing onto a roof.
But a lot of their neighbours “were swept by the water,” he said.
“Water came like a tsunami and destroyed most things. We were prisoners on the roof,” he told AFP after they were rescued by boat.
The city of Beira, Mozambique’s second largest city and a major port, was immediately cut off after the storm. According to the Red Cross, the cyclone damaged or destroyed 90 percent of the city of half a million people.
President Nyusi, speaking on Tuesday after attending a cabinet meeting in the ravaged city, said the confirmed death toll stood at 202 and nearly 350,000 were “at risk”.
The government had declared a national emergency and ordered three days of national mourning, he said.
“We are in an extremely difficult situation,” Nyusi said, warning of high tides and waves of around eight metres (26 feet) in the coming days.
On Monday, Nyusi had said he feared more than 1,000 had died and more than 100,000 people were in danger.
Mozambique, one of the poorest countries in the world, was also hit by deadly floods in 2000 that killed 800 people and left at least 50,000 homeless.
The storm also lashed eastern Zimbabwe, leaving around 100 dead, a toll that could be as much as 300, local government minister July Moyo said after a cabinet briefing.
“I understand there are bodies which are floating, some have floated all the way to Mozambique,” he said.
“The total number, we were told they could be 100, some are saying there could be 300. But we cannot confirm this situation,” he said.
At least 217 others are missing and 44 stranded, officials said.
Worst hit was Chimanimani in Manicaland, an eastern province which borders Mozambique.
Families started burying their dead in damp graves on Monday, as injured survivors filled up the hospitals, an AFP correspondent said.
Military helicopters were airlifting people to Mutare, the largest city near Chimanimani.
The storm swept away homes and bridges, devastating huge areas in what Defence Minister Perrance Shiri said “resembles the aftermath of a full-scale war”.
Some roads were swallowed by massive sinkholes, while bridges were ripped to pieces by flash floods.
Aid ramps up
The UN World Food Programme (WFP) said it was mobilising aid for some 600,000 people, saying the world did not yet appreciate the scale of the “massive disaster”.
So far, it has dispatched more than five tonnes of emergency provisions to the affected areas.
“WFP aims to support 500,000 to 600,000 people in the coming weeks,” spokesman Herve Verhoosel told reporters in Geneva.
“I don’t think that the world (has) realised yet the scale of the problem.”
In Malawi, 920,000 people have been affected by the cyclone and 82,000 people have been displaced, the UN said.
“OCHA (the Office for the Coordination of Humanitarian Affairs) has deployed resources to support assessments and information management, and UNICEF is deploying additional supplies to affected areas including tents, water and sanitation supplies and learning materials to affected children,” it said.
