porto b fc,That ocean life helps produce clouds is elementary science. Water evaporates, forms clouds, the clouds produce rain, the water goes back into the ocean, and the cycle repeats. That is the science story they tell us in primary school, anyway. However, "It turns out that this story of cloud formation was really incomplete," says Tim Bertram, a UW–Madison professor of chemistry.  

Bertram is a part of the research team from various institutions including the University of Wisconsin–Madison, the National Oceanic and Atmospheric Administration and others that have discovered that the existing clouds keep new ones at bay. Clouds don’t allow clouds to form. Sounds bizarre? Allow us to explain how they came to the conclusion.,bbc iplayer

Remember the last time you stood by the seaside and breathed in a whiff of salty air? Remember that pungent, rotting odour that we all associate as a characteristic of the sea? It is the odour of sulphur.,osm rummy

football games 2018 download free,Marine plankton like bacteria, archaea, algae, protozoa and drifting or floating animals in the sea breathe more than 20 million tons of sulphur every year. This goes into the air in the form of dimethyl sulphide (DMS). The DMS then transforms into sulphuric acid, which in turn helps produce clouds by giving a site for water droplets to form. Over the scale of the world's oceans, this simple process can affect the entire climate. This is how climatologists have been explaining the formation of clouds and rain for generations now.

However, baseball zone ,new research published on Monday in the Proceedings of the National Academy of Sciences reveals that more than one-third of the DMS emitted from the sea gets dissolved in water droplets in clouds that already exist, and therefore cannot be used in the formation of new clouds. Effectively, what is needed to form new clouds is eaten up by the old clouds and thereby not allowing new clouds to form.

A few years ago the researchers’ team had discovered that DMS first turns into a molecule known as HPMTF before becoming sulphuric acid. This HPMTF is a new molecule and had never been identified before. For the new study to capture detailed measurements of these chemicals over the open ocean both inside of clouds and under sunny skies, the team used NASA-owned, instrument-laden aircraft.,soccernet down

"This is a massive DC-8 aircraft. It's a flying laboratory. Essentially all of the seats have been removed, and very precise chemical instrumentation has been put in that allows the team to measure, at very low concentrations, both the emitted molecules in the atmosphere and all of the chemical intermediates," says Bertram.,football games to play online

The team discovered from the flight data that HPMTF readily dissolves into the water droplets of existing clouds, which permanently removes that sulphur from the cloud nucleation process. In cloud-free areas, more HPMTF survives to become sulphuric acid and help form new clouds.,gremio fc

"This work has really reopened this area of marine chemistry," says Bertram. And we couldn’t agree more.,porto b fc

j choinski,The new findings will significantly alter the prevailing understanding of how marine life influences clouds. This, in turn, will prompt the climatologists to change the way they predict how cloud formation responds to changes in the oceans.

And accurately predicting clouds is important to understanding the effects of climate change. Clouds play significant roles in the global climate by reflecting sunlight back into space and controlling rainfall.,bonus 918kiss
