The advantage of flowering plants is Flowers attract insects that transport gametes.
Because they are often showy and endowed with nectaries, the flowers of angiosperms attract animals, such as small invertebrates, birds and bats. Such living beings, when coming into contact with several flowers of the same species, provide the meeting of pollen grains with female reproductive structures.
Flowers help to maintain air quality. They are natural humidifiers purifying the place and releasing oxygen. They also work as aromatizers by exhaling their fragrances.

El Niño, and its La Niña counterpart, are large-scale oceanic phenomena of the equatorial Pacific Ocean, affecting the wind regime, sea temperature, and precipitation. El Niño and La Niña correspond to the two opposite phases of the coupled ocean / atmosphere phenomenon called ENSO (El Niño / Southern Oscillation).
Originally, the name El Niño was attributed by Peruvian fishermen to the small invasion of hot water that occurs every year along the coasts of Peru and Ecuador around Christmas - hence its name: in Spanish, El Niño means the child Jesus. By extension, the climatic phenomenon corresponding to the increased warming of surface waters near the coast of South America is now called El Niño. We know that it is linked to a cycle of changes in atmospheric pressure between the east and west Pacific, coupled with a cycle of ocean current along the equator.
Only ENSO has such a marked global impact. The other two ocean basins, Indian and Atlantic, are too small to allow such an important coupling between atmospheric and oceanic circulation, even if they also undergo deep water upwelling and trade winds.
