Low pressures

We cannot forget the havoc caused by the cyclonic storms and tornados on our earth. These phenomena even today treat man' carefully created structures as paper toys. Science has some answers, though they are far from perfect and at least can only help in advance warning to some extent.

We believe that all meteorological phenomena are due to low and high pressures of the atmosphere which are caused by the irregular heating of the air by the sun. Only tides are supposed to be an exceptional process mainly associated with the position of moon. The rotation of the air currents in the cyclones or tornados are believed to be due to the rotation of the earth. Many lives have been lost due to cloud bursts in different parts of the world. A cloud burst is a sudden condensation of water vapours of the cloud in a very short time. Many of us were of the view that cloud burst takes place in mountainous areas  where dense clouds get trapped between high mountains and more saturated clouds continue to reach there from a funnel type entrance. But, as we have observed the cloud bursts in plain areas too, there may be some other factor as well to trigger a cloud burst.

Every one must have watched how particles of smoke get uniformly distributed in a closed room in due course of time. Similarly, the law of diffusion help gases get uniformly distributed in an open space. But, this is not the case with clouds as their molecular structure takes different shapes depending on the temperature and pressure of space from where the wind is passing. Mostly, we give more importance to temperature and humidity than the distribution of pressures for critical meteorological events. The meteorological observatories are generally equipped to record wind direction, humidity, temperature and rainfall. We don't give much importance to gravitational and pressure variations on hourly observation basis along with other general observations.

There are some meteorological events like tornados which lasts only for less than an hour. The destruction caused by a tornado is by its violent winds, by the tremendous lifting effect of updrafts, and by the explosive effect of a sudden drop in the atmospheric pressure. Winds may whirl around the low pressure centre of a tornado at the rates up to 200 to 400 Km./hr. or even more. Updrafts associated with tornado may attain speeds of 100 to 200 Km./hr., and thus it acts as a giant vacuum cleaner. Barometer pressure may drop greatly as 1 to 2 inches of a mercurial barometer. Thus within 10 to 20 seconds pressure may change by as much as 400 lb/Sq.ft., and closed buildings explode outward, roofs are blown off and objects like cars are blown away like tree leafs.

Just how tornados originate is still uncertain, and their precise locations cannot be forecast. These sudden meteorological events must not always be associated with the heating of the air by the sun but may be due to some sudden changes of pressures in localised areas under well defined boundaries. At least one event can be mentioned here where some unique observations were made during a full solar eclipse. Change in weather was observed on 16th Feb. 1980 during full solar eclipse at the Meenambakkam weather observatory which recorded sudden fall of 2.5 degree centigrade in temperature between 3 and 4 p.m. The humidity was up by 12 percent and the atmospheric pressure dropped by 0.5 milibars. These readings show that the rise in humidity may be due to the fall of temperature and pressure. And the fall of temperature may be due to the expansion of the air molecules. All these changes can be associated with sudden fall of gravitational field at the localised place of eclipsed area. So, the push ray particles that can be mainly responsible for change of gravitational field within well defined boundaries may be responsible such extreme short lived localised events.

The pressure of the air at different layers of the atmosphere is due to the weight of the air molecules. And we know that the weight of air molecules is due to the so called gravitational attraction between the earth and the molecules of air. In fact the weight of air molecules is due to the resultant force on them by the push rays coming from all over the universe. These push rays just like light rays are forming eclipse like shadows of low pressure areas not only by the sun and moon but by some other nearby planets too. The path of many tornados are more likely to follow a definite straight line pattern just like solar eclipse shadow paths as they may be caused by some unique position of three or more heavenly bodies.

So, I believe that the variation of gravitational field plays a great role in some of the major meteorological events. The gravitational field, which is due to the push rays of the universe, falls suddenly on a very limited area on the surface of the earth when the effected area receives weak intensity of push rays due to two or more heavenly objects coming in straight line with that area.
