New atmospheric model predicts downpours on Earth


New atmospheric model predicts downpours on Earth

Washington, Nov 5 (Prensa Latina) An atmospheric model made it possible to discover the cycles of deluge on the primitive Earth, unknown until now, where experts predicted that they will be repeated in hundreds of millions of years, it was reported.

The research conducted at Harvard University, in the United States, investigated the intensity and magnitude of these intense periodic rains that interrupted periods of extreme heat, in which precipitation was practically non-existent in the initial moments of our planet, according to the journal Nature.

Scientists Jacob Seeley and Robin Wordsworth, authors of the research, increased the sea surface temperature to around 54 degrees Celsius, within the framework of the model created, to simulate the real conditions existing on primitive Earth.

They increased the carbon dioxide (CO2) present in the atmosphere by a magnitude of about 64 times the current amount and, at the same time, increased the brightness of the Sun by about 10 percent, the article continued.

By recreating the conditions that characterized the Earth in the past, it was possible to experience the features of intermittent cycles of dryness and deluge.

At these temperatures, the atmosphere registers strange phenomena, at least according to our current vision.

The researchers noted that these cycles of deluge constitute a new atmospheric state, which will be repeated in the future as the Sun continues to shine.
