Bacteria modify weather

In the upper troposphere (6 to 10 miles) is home to many microorganisms. Their composition varies especially in tropical storms, soobshayut NASA specialists and Georgia Institute of Technology in an article published in the Proceedings of the National Academy of Sciences.

Microorganisms play an important role in the life of the atmosphere — they, in particular, influence the formation of clouds and precipitation. At altitudes lower than 5 kilometers of microbial cells up to 3 microns comparable to the number of ice particles of the same size. Living cells can "work" condensation nuclei and induce precipitation, or, conversely, to prevent them. However, until now scientists had very little is known about the microorganisms that live in the upper atmosphere.

Scientists at NASA program to study tropical storms in 2010 had a number of flights in the Caribbean Sea in the DC-8 aircraft on board which the equipment was installed to collect air samples. Of the samples using a filter system were isolated microorganisms, which were then subjected to genomic analysis.

As it turned out, at altitudes up to 10 kilometers proportion of bacterial cells is about 20% of particles ranging in size from 0.25 to 1 micron. In this case, the bacteria is about 10 times larger than the fungal cells. Total found 17 different classes of bacteria. Some of them can eat carbon compounds, many of which particles in the atmosphere. In this case, the species composition of microorganisms from different air masses depend on their origin. Air, brought tropical storm "Earl", differed in the bacterial composition of the air hurricane 'Karl'.

Site "Survival in the wild nature", glad to see you. If you come to us, it means you want to get complete information about survival in a variety of extreme conditions, in emergency situations. Man, throughout the development, sought to preserve and protect themselves from the various negative factors surrounding it - cold, heat, hunger, dangerous animals and insects.

Site structure "Survival in the wild nature" is simple and logical, selecting a specific section, you will find information. You will find on our website recommendations and practical advice on survival, unique descriptions and pictures of animals and plants, turn-based scheme to trap wild animals, tests and reviews of travel gear, rare books on survival and wildlife. The site also has a large section devoted to video on survival survivalist-known professionals around the world.

The main theme of the site, "Survival in the wild nature" - is to be ready to be in the wild, and the ability to survive in extreme conditions.

The Survival in the wild nature - how correctly to behave, it having appeared in an emergency situation. Ability to find a way out from any situation: to kindle a fire, to put traps, to prepare food, to arrange dwelling and a lodging for the night; to learn to knit knots, to clear water, to be guided by districts, correctly to choose equipment, a knife. Also you can download directories to tourists, encyclopedias survivals, video Bear Grills to Survive at any cost (Man vs. Wild).
