MEGHAM (THE CLOUD) PART 1 Dear friends,
Recently while travelling inplane to Bangalore, the plane was going above, in middle and below duringlanding and takeoff. I thought at that time to write a posting on cloud.Information are compiled and posted with my additions. Sincerely, Gopala krishnan 12-1-2011. Reposted on 5-2-2021 after editing and updating information. 1. Megha dootham I have studied in the 9thstandard Megha dootham, a sandesa kavyam (poetry with substanceto carry a message) by Kavi Kalidasa. In this a Gandharva is sending a messageto his wife making cloud as messenger. On those days I knew cloud hasdifferent colours, when it is very dark and thick more rain is expected withthunder and lighting. The two heavy rain periods in Kerala are Thulavarsham and Karkitaka pathi.Thula varsham is told so, because it is in the Malayalam month Thulam, October-November. Karkitaka pathi is told sobecause, it start in the middle of Karkitakam. Month of June when the schoolsre open after vacation. 2. Megha Shyamala varnam Lord Krishna is referred to haveMegha shyamalavarnam. (Skin having light blue colour). Earlier I could notdigest colour of Blue for humans, but later seeing different type of blood in nsects,I could digest the different colour of blue for Krishna and dark for Balarama. 3. Sky without cloud. Though I am not a sky watcher, lookingat the sky without cloud and full of stars is very entertaining to me. We couldsee bright, less bright and twinkling stars. Very late I knew planets would not twinkle and seeing Budhaand Sukra in the sky and locating them was an excitement. 4. Sky with cloud Normally we see sky with cloudand moving and standing forming different images. Watching the sky with thewhite moving cloud, which would not rainin summer, is also enjoyable and makes one think and think. Suddenly moongetting hidden, then appearing and again disappearing in clouds… 5. Passing through cloud First time while going in theflight, seeing clouds belowthe flight was new, though others have told and heard earlier.Seeing is believing, clouds need not form at very high altitudes. 6. Changing face like a cloud. This phrase is very often usedwhen somebody makes an expression of least liking by another. 7. What is cloud? A cloud is a visible mass ofwater droplets or frozen ice crystals suspended in the atmosphere above the surface of the Earth or otherplanetary bodies . This means clouds can be with other plants. Clouds in the Earth's atmosphere are studied in the NEPHOLOGY or cloudphysics branch of meteorology. 8. How cloud is formed and stands at heights? Weknow Sun is a hot planet and light is coming from it, travelling light years(Very very long distance). Lightfrom Sun reach us after a lot of travelling. Incominglight generated by the Sun reflects back when itreaches the Earth'ssurface; a process that warms the air closest to the ground. Reflction means going back to the source. Light reflecting from our bodymake us see ourselves in the mirror. Thiswarm air tends to absorb moisture in the form of invisible water vaporfrom water bodies (streams, lakes, river, sea etc), moist ground, and from plants. Warmmoisture-laden air is inherently unstable and tends to rise to higher altitudes where the surroundingair is colder. Atmospheric pressure decreaseswith altitude( Probably a practical done by many of us as students).(Weight at Himachal Pradesh for an apple can be a few grams less comparing to Chennai) Sowhen air rises, it expands in a process that expends energy whichcauses the air to cool. Cold air holds less water vaporthan warm air, so clouds are formed when the air is lifted and cooled to thepoint at which it begins to shed vapor it can no longer retain. The vapor begins to condenseonto airborne hygroscopic particles like dust and salt fromsea spray and becomes visible as cloud. So cloud is formed on dusts. Weknow rain and cloud are related. My next posting will be why all clouds do not make rain, how rain occurfrom clouds etc. -- You received this message because you are subscribed to the Google Groups "Thatha_Patty" group.
