(.#A.073).- It sets fire to Australia and makes locusts rain in Africa. Feb 10, 2020. It sets fire to Australia and makes locusts rain in Africa - Feb 10, 2020. The same weather phenomenon is responsible, at least in part, for fires in Australia and the invasion of billions of locusts which are currently devouring crops in East Africa, the Middle East and South West Asia. This is the dipole of the Indian Ocean, This "Indian El Nino" causes a temperature variation between the west and the east of the Indian Ocean, which can lead to sometimes brutal consequences. EASTERN FIREPLACE • Swarms appeared in December 2019 in India and Pakistan (worst invasion in 27 years). • Some then moved to lay eggs, in Iran and further south-west. Positive phase of the Indian Ocean dipole : The dipole is currently in a positive phase: the water is warmer than normal in the west, colder in the east. The cooler water is denser, heavier, so it evaporates less. As a result, it rains less. This worsens the dryness and promotes fires. COUNTRIES AFFECTED : • Iran • Saudi Arabia • Sudan • Ethiopia • Kenya • Pakistan • India AFRICAN FIREPLACE • Swarms first formed in December 2019 in Ethiopia, devouring 90% of the crops. • In Kenya, swarms are 60 km long and 40 km wide: unprecedented in 70 years. The heat of the Indian Ocean leads to greater precipitation, which favors the emergence of locust swarms. Note : A locust can swallow its weight in food (2 grams). A swarm of one square kilometer consumes the same amount of food in a day as 35,000 people. AUSTRALIA • Strong dry westerly winds worsened the situation by stoking fires. F I N.
