Title: South West (Nigeria)
Content: Ekiti ; Lagos ; Ogun ; Ondo ; Osun ; Oyo South West Nigeria is one of the geopolitical zones of Nigeria, consisting of the following states; It is a Yoruba region, land and Yoruba speaking area, with different dialects even within the same state. The weather conditions vary between the two distinct seasons in Nigeria; the rainy season (March - November) and the dry season (November - February). The dry season is also the bringer of the Harmattan dust; cold dry winds from the northern deserts blow into the southern regions around this time.
Title: Geography of Nigeria
Content:  The tropical maritime air mass (MT) is responsible for Nigeria's rainy season. This wind begins in February in the southern part of Nigeria while it takes longer for the wind to fully cover the whole of the country, reaching the northern part of Nigeria in June. Its presence a result of the northward retreat of the Harmattan. The northward retreat of the tropical continental air mass (CT) is caused by the sun's northward shift from the tropic of capricorn in the southern hemisphere to the tropic of cancer in the northern hemisphere. This shift begins from February and ends in June, when the sun is fully overhead at the tropic of 
Title: Onikwu
Content:  Nigeria, like the rest of West Africa and other tropical lands, has only two seasons. These are the Dry season and the Rainy season. The dry season is accompanied by a dust laden airmass from the Sahara Desert, locally known as Harmattan, or by its main name, The Tropical Continental (CT) airmass, while the rainy season is heavily influenced by an airmass originating from the south Atlantic Ocean, locally known as the south west wind, or by its main name, The Tropical Maritime (MT) airmass. These two major wind systems in Nigeria are known as the trade winds. The region Onikwu/Ndoni is flood prone communities, this is because the inland part of Rivers state consists of tropical rainforest; towards the coast the typical Niger Delta environment features many mangrove swamps, beside that the communities lies along the Niger Delta Central coastal region. In October 2012, villages like Ndoni, Ase-Azaga, Isukwa, Odugiri. Agwe, Onikwu, Ugbaja, Isala and Ogbe-Ogene were badly hit by the flood.
Title: Geography of Nigeria
Content:  continental air mass from the Sahara is weakened by the overheating of the land surface. This transfer of heat in turn causes the atmosphere to expand and become lighter. The air mass loses its strength around February in the southern part of Nigeria to June in northern Nigeria and begins to retreat coupled with the rising of air in form of convection within this air mass, further weakening the dominance of the wind over West Africa. The air mass finally retreats from most of Nigeria around April to May. The sun's rays enters into the atmosphere of Nigeria more intense than it does during the Harmattan, which contains dust and haze. 
Title: Geography of Nigeria
Content:  During this northward migration of the sun as a result of the earth tilting along its axis, the sun crosses the equator (around March), moving over West Africa. West Africa comes directly under the sun at this time. The whole of West Africa is heated intensely as result of the increased insolation. Temperatures can climb as high as 35 °C over West Africa during this time. Temperatures in the northern part of Nigeria can go as high as 48 °C in cities like Maiduguri. The high temperatures coupled with an increase in insolation cause a region of low pressure to develop over West Africa and Nigeria between March to May. The 
Title: Energy in Nigeria
Content:  Wind turbine generation is another developing energy source in Nigeria. Wind speeds in Nigeria typically range from 2–9.5 m/s. With such low wind speeds, investments and interest in wind energy have not been as high as solar power. However, wind power could be advantageous to rural and agricultural areas. Wind power would also be beneficial in the Southeast with wind power potentials higher than 4 m/s, and in the North where wind speeds reach up to 6 m/s at a 10 hub height. Initiatives such as Nigeria's National Renewable Energy Plan are beginning to set forth goals in wind turbine implementation. However, with insufficient data and its status as a relatively new technology, development overall has been slow and challenging.
Title: Geography of Nigeria
Content:  in the southern part of Nigeria records a maximum of 28 °C for its hottest month while its lowest temperature is 26 °C in its coldest month. The southern part of Nigeria experiences heavy and abundant rainfall. These storms are usually convectional in nature because of the region's proximity to the equatorial belt. The annual rainfall received in this region is very high. The Niger Delta receives over 4000 mm of rain annually. The rest of the southeast receives between 2,000 and 3000 mm of rain per year. The southern region of Nigeria experiences a double rainfall maxima characterised by two high rainfall peaks, 
Title: Geography of Nigeria
Content:  bright and sunny, the sun's heating of the land in the mornings and afternoons sets up convectional currents, these currents rise vertically, cumulonimbus clouds are formed, and torrential downpours can occur in the afternoon. The African easterly wave is another major contributor of rainfall during the summer monsoons months of May to September. The nature of this wave changes at about 15 degrees north latitude. The waves that pass south of this latitiude carry moisture and create convection that leads to rain clouds. Nigeria's location in the wetter part of the easterly waves south of the 15 degrees north latitude creates wetter climatic conditions for Nigeria, especially during the monsoons.
Title: Awka
Content:  Awka is in the tropical rainforest zone of Nigeria and experiences two distinct seasons brought about by the two predominant winds that rule the area: the southwestern monsoon winds from the Atlantic Ocean and the northeastern dry winds from across the Sahara desert. The monsoon winds from the Atlantic creates six months of heavy tropical rains, which occur between April and July, followed by a short dry period in August lasting two to three weeks with the rain resuming in September and October. This is followed by five months of dryness (November–March) marked by a Harmattan wind, also known as Ugulu in Igbo, which is a particularly dry and dusty wind which enters Nigeria in late December or in the early part of January and is characterized by a grey haze limiting visibility and blocking the sun's rays before dissipating and leading to extreme dry heat in the latter months of February and March. The temperature in Awka is generally 27–30 °C between June and December but rises to 32–34 °C between January and April, with the last few months of the dry season marked by intense heat.
Title: Climate of south-west England
Content:  The south-west is the second most exposed area of the United Kingdom; second to western Scotland. The strong winds are caused by deep depressions across or close to the British Isles. Winds are stronger in the winter-half year, as the depressions' strength and frequency increase. The lightest mean wind speeds are in summer. The speed of peak gusts and mean wind speed follow a similar pattern throughout the year. Mean wind speeds are generally lower to the north-east of the region and in inland areas. Yeovilton, lowland Somerset, has a mean wind speed that is two thirds that of St. Mawgan
