Nigerian Meteorological Agency (NiMet) has warned that most parts of Nigeria would experience intense hazy weather conditions otherwise known as harmattan in December 2017 and January 2018.
Its Director-General, Prof. Sani Mashi, told the News Agency of Nigeria (NAN) yesterday in Abuja that the North-east part of the country had begun to witness hazy conditions.
Mashi said the North-easterly wind, one of the two air masses that controlled the country’s climate, had begun moving inward from the North-eastern part of the country in the last couple of days.
“Harmattan is definitely going to set in very soon and it has already started setting in the northeastern part of the country.
“The air mass is moving towards the country from northeastern direction, so from December and January it will cover virtually all the country.
“That is why we are predicting that in December and January, there is going to be much problem of dust and haze in most parts of the country.
“Normally, it last for about 70 days and the effect will be from one condition to another because there are some local conditions that could be modified.
“So, you will discover that some locations that are open that do not have hills, there could be local disturbance that would not allow the flow of air in that location.
“And because of that you will discover that air will be flowing and therefore the haze will be more intense,” he said..
Mashi explained that while the air mass from the South-western part is moist and facilitated rainfall, the North-easterly air mass is normally dry and dusty thereby giving rise to hazy conditions.
According to him, this situation will continue up till December and January in different parts of the country and it is expected to be more serious in the northern part.
NiMet boss said that cessation of rainfall had occurred in many parts of the North, adding that its impact on food production was yet to be ascertained since farmers were yet to give feedback.
