Where does it come a cloud? Where are the clouds going?Information about the two it becomes very important to forecast extreme weather, to help make preparations to deal with it.
The researchers were then analyzed through the rain drops and ears portrait snow three dimensions, taken from outer space.
One such studies are US Space Agency (NASA). As quoted by the Daily Mail , they do a collaboration with Japanese researchers to create a 3-dimensional view raindrops to know their origins in a particular cluster of clouds.
Cooperation researchers NASA by the Japan Aerospace Exploration Agency Global Precipitation Measurements (JAX GPM) was studying 'the particle size distribution' contained in the clouds.

'Distribution' is meant that the number of drops of rain and snow grains of various sizes in different places in the cloud that is being observed.
Look, the drops of rain in a storm cloud is composed of various sizes. In the end, the drops that fall as rain or snow.
Well, at the core of the cloud that is being monitored, the drops were generally larger in size as they collide with each other and merge. While the smaller size is in the periphery and in a higher place in the cloud.
Comparison of the number of drops of various sizes that allowed the researchers to understand precisely how the rainfall produced by a storm.

Previously, researchers have only limited data and must make assumptions about the ratio of the number of droplets of various sizes earlier.
Said Joe Munchak, a meteorologist and researcher at the Goddard Space Flight Center of NASA, "Spreading the droplet size is one of many factors that determine how big the storm is, how long it happened, and how much rainfall produced. Prior to this we have never seen differences in global measures of drops of water. "
"Without knowing the relationship or ratio of the number of droplets droplet size by the number of medium and small size, difficult to estimate the rain fell. The impact of long-term, to help predict flash floods."

The distribution of the size of the droplets determines the growth of the storm for changing the speed of evaporation (evaporation) of rain fell. Droplets smaller tends to evaporate more quickly so that cool the air around.
It can blow down the strong winds that create mischief in the earth's surface, but instead may also weaken or even interrupted the storm.
Munchak said again, "Measurement GPM will greatly help predict these complex interactions, some of which depend on the droplet size distribution."
With this new data, researchers can make more precise predictions and can be used to improve models of weather that already exist.
