Weather is not the same everywhere. Perhaps it is hot, dry and sunny today where you live, but in other parts of the world it is cloudy, raining or even snowing. Everyday, weather events are recorded and predicted by meteorologists worldwide.CLIMATE: CLIMATE Climate in your place on the globe controls the weather where you live. Climate is the average weather pattern in a place over many years. So, the climate of Antarctica is quite different than the climate of a tropical island. Hot summer days are quite typical of climates in many regions of the world, even without the affects of global warming.DIFFRENCE BETWEEN WEATHER AND CLIMATE: DIFFRENCE BETWEEN WEATHER AND CLIMATE WEATHER Weather is the day-to-day state of the atmosphere, and its short-term (minutes to weeks) variation. Popularly, weather is thought of as the combination of temperature, humidity, precipitation, cloudiness, visibility, and wind. We talk about the weather in terms of "What will it be like today?", "How hot is it right now?", and "When will that storm hit our section of the country?" CLIMATE Climate is defined as statistical weather information that describes the variation of weather at a given place for a specified interval. In popular usage, it represents the synthesis of weather; more formally it is the weather of a locality averaged over some period (usually 30 years) plus statistics of weather extremes.HEATING OF THE EARTH’S ATMOSPHERE: HEATING OF THE EARTH’S ATMOSPHERE The Earths atmosphere dose not get heated directly by the heat of the sun. since the atmosphere is largely made of the gases , most of the solar radiation passes through its to the earth. The earth being solid gets heated.Modes of transfer of heat: Modes of transfer of heat There are four modes of transfer of heat. Convection Conduction Radiation advectionConvection: Convection Convection is the movement of molecules within fluids (i.e. liquids, gases and rheids). It cannot take place in solids, since neither bulk current flows or significant diffusion can take place in solids.Conduction: Conduction in heat transfer, conduction (or heat conduction) is the transfer of thermal energy between neighboring molecules in a substance due to a temperature gradient. Radiation: Radiation Radiation is a collection of recordings from Cabaret Voltaire during their most accessible period. studios.Advection: Advection Advection, in chemistry and engineering, is a transport mechanism of a substance, or a conserved property, by a fluid, due to the fluid's bulk motion in a particular directionFrom Pawas Kalra Kartik Arora Ritabh Gupta Nitin Dabas: From Pawas Kalra Kartik Arora Ritabh Gupta Nitin Dabas You do not have the permission to view this presentation.
