climate of a small area within a larger area‚ my garden. I was given the task of investigating the microclimate of my garden and recording what I found. The warmest place was site 3 with a temperature of 13 degrees Celsius In site 3 there is a low albedo so heat is absorbed therefore the temperature is higher here on a warm day the aspect of this site is south west so this results in this part of the garden being warmer‚ because places facing the sun are warmer than those in the shadows‚ in Britain

Kayla Richards 3/12/14 1A “Global Climate Change Essay” Global Climate change is a term used to describe a gradual increase or change within the average temperature of earth’s atmosphere and its oceans. Global climate change is a rising issue in today’s society. There are various factors as to why the climate is changing; the factors are both human and natural. The human activities that cause climate change are burning fossil fuels‚ driving cars‚ and deforestation. The human causes are widely

In the outer limits of our solar system there is a planet unlike any other‚ Pluto. Pluto was discovered in February of 1930 by an American astronomer‚ Clyde Tombaugh. It is the only planet to have been discovered by an American. All though we have known of the existence of Pluto for over thirty years now‚ there are still many mysteries surrounding this celestial body. Being the farthest planet has made it difficult to study Pluto‚ Adding to the obscurity of this strange planet is that the capability

Arctic. As temperature rises‚ ice melts. This causes many problems. A change to the reflectivity on the surface of the earth; which is called the albedo‚ affects the amount of solar radiation absorbed by the Earth. As Arctic sea ice continues to melt it exposes open water which is less reflective and causes the albedo to decrease. The reduction in albedo allows more light to be absorbed by the ocean. As the ocean water warms‚ more heat is added to the air creating a positive feedback and driving Arctic

CRITICALLY EVALUATE THE FACTORS INFLUENCING THE GLOBAL HEAT BUDGET - 40 MARKS The global heat budget is the balance between incoming insolation‚ and outgoing radiation from Earth. There are many factors that influence this heat budget‚ some of which are more important than others. In this essay I am going to describe and explain each factor involved. Insolation is the incoming energy from the sun in shortwave ultraviolet (UV) radiation. The distribution of insolation over the Earth’s surface

ATMOSPHERE – OCEAN INTERACTIONS :: LECTURE NOTES 1. Introduction to the Atmosphere and Ocean J. S. Wright jswright@tsinghua.edu.cn 1.1 O VERVIEW This chapter outlines the main features of the atmosphere–ocean system and motivates the deeper examination to follow. The character of coupled atmosphere–ocean interactions is briefly introduced. Simple energy balance models are derived and used to illustrate the fundamental mechanisms behind variations of temperature with altitude

Climates and Oceans- 1. With coastal climates‚ the locations are on the windward side‚ meaning the weather patterns move from the ocean to land‚ giving them mild summers and cool winters. This means that there isn’t a very large temperature range for coastal climates. Inland climates are more of the land heating and cooling‚ because they heat to high temperatures in the day and then cool a great amount at night. Also‚ the weather patterns are moving from land to water‚ creating warmer summers and
