Storms Are Getting Stronger and More Frequent

It is accepted that we are getting more rain though it evaporates very quickly and leads to drought. The cycle of evaporation and rain is speeding up. The planet it heating up as the poles are melting. Glaciers are reducing in size with the water flowing into the oceans thus increasing the height of the sea. There is one thing that has not been studied in depth - wind.

Tornadoes are getting stronger. Furthermore, storms with high winds are becoming more frequent and stronger. Over the last decade storm winds have become five per cent faster. The highest strength winds have increased by ten per cent. Analysis of wind change is not that easy. Wind does not show up in satellite pictures. Special equipment such as radar altimeters are put onto satellites. They get data by scanning for echoes. The frequency and strength of storms is definitely increasing.

It is not yet proven to be due to global warming. This could be a cyclical phenomenon. Nonetheless, it is drawing a long bow not to presume it is an aspect of global warming. Rising seas with stronger storms will cause more erosion in coastal regions.

A Shock in Space

Something is happening - out there! Yes, something mysterious has occurred in space. Astronomers are aghast at the total disappearance of a broad ring around Jupiter. This is a shock and totally unexpected. Things in space are supposed to be quite stable.

The ring was not on a picture taken on May 8. The band was very large, twice as broad as the diameter of Earth. A view with binoculars clearly shows that the "bottom" half of the planet is now all white. The twin banded planet is now "held together" by a single band - quite disconcerting.

Have no fear. The disappearance could be only temporary. Jupiter's second belt could be covered by cloud higher in the planet's atmosphere. Ammonia can cause ice crystals to form which develops into cirrus clouds. Wind patterns have probably changed on the planet. This has led to a climate change. Just why the bands are brown is a mystery anyway. Only a few probes have been sent to Jupiter so knowledge about it is limited. Every 15 years or so the South Equatorial Belt fades, but his time it has become fully invisible. Its reappearance is expected to be entertaining with bursts of vortices and storms spreading out from a central point gradually covering the whole planet. This will occur in a few weeks. Don't miss it. Keep your eyes on the stars.
