Elements of Climate and weather

Elements OF Climate AND WEATHER   Climate is decided by a region’s climate system. A climate system has few major components: the Atmosphere, the layer, the cryosphere, and the land surface. The atmosphere is that the most variable a part of the climate system. The composition and movement of gases encompassing the planet will change … Read more

Chemical Reaction

The Rate of a Chemical Reaction can be defined as the amount of the reaction which occurs in unit time. The rate of a reaction is measured by choosing certain properties of the reaction which will indicate how far the reaction has gone, and whose magnitude can be observed with time without disturbing the reaction. … Read more

Acids, Bases and Salts.

Acid An acid is a substance which forms H+ ions as the only positive ion in aqueous solution. Examples:- Hydrochloric acid dissolved in water forms H+ and Cl– ions HCl —> H+ + Cl–   Sulphuric acid dissolved in water forms H+ and SO42- ions H2SO4 —>2H+ + SO42-   Nitric acid forms H+ and NO3– ions when dissolved in water HNO3 —> H+ + NO3–   … Read more

El Nino

El Nino El Niño is the name given to the occasional development of warm ocean surface waters along the coast of Ecuador and Peru. When this warming occurs the usual upwelling of cold, nutrient rich deep ocean water is significantly reduced. El Niño normally occurs around Christmas and usually lasts for a few weeks to a few months. Sometimes … Read more

Atmospheric Disturbances

The atmospheric disturbances which involve a closed circulation about a low pressure centre, anticlockwise in the northern Atmosphere and clockwise in the southern hemisphere are called Evaporation and Condensation: dew, frost, fog, mist and cloud, rainfall types  Evaporation    Evaporation is the process of which water changes from its liquid state to gaseous form. This … Read more

 Evaporation and Condensation, and so governs the degree of stability of the atmosphere. 3. As relative humidity is directly associated with the temperature of the air, it affects the character and kinds of cloud formation and precipitation.   Temperature is the degree of hotness or coldness of an object. We tend to observe … Read more

Mains Booster-Weather forecast

Weather forecast There are two ways for weather forcasting: Short-range forecasting Meteorologists can make somewhat longer-term forecasts (those for 6, 12, 24, or even 48 hours) with considerable skill because they are able to measure and predict atmospheric conditions for large areas by computer. Using models that apply their accumulated expert knowledge quickly, accurately, and … Read more
