reaction paper for the article: TROPICAL CYCLONES ‘LIKELY TO INTENSIFY’ According to the article‚ Tropical cyclones hitting East Asia have grown increasingly fierce in the past 30 years and are likely to intensify further with global warming. Noticeable increases of greenhouse gases over the globe could influence rising sea surface temperature and change large-scale atmospheric circulation in the Western North Pacific‚ which could enhance the intensity of tropical cyclones hitting land over East

Describe and explain the seasonal variations in climate in a tropical region (10 marks) The seasonal variations in climate‚ in a tropical region‚ which includes temperature‚ precipitation and wind direction‚ are due to a number of factors. The tropical continental climate in Africa‚ north of the equator‚ can be described as transitional‚ as it is between the rainforest margins of the central African rainforest and also

CHAPTER ONE INTRODUCTION 1.0. Soil – transmitted helminths Soil–transmitted helminths (STHs) are included in the list of the world’s neglected tropical diseases (Molyneux et al.‚ 2005). STHs are major public health problem especially in the developing nations. The species of soil-transmitted helminths that infect humans are concentrated in the developing world‚ and these include the large roundworm Ascaris lumbricoides‚ the whipworm Trichuris trichiura‚ and the hookworm Ancylostoma duodenale

Causes and consequences of reduced biodiversity in tropical rain forests In many tropical countries‚ the majority of deforestation results from the actions of poor subsistence cultivators. However‚ in Brazil only about one-third of recent deforestation can be linked to cultivators. A large portion of deforestation in Brazil can be attributed to land clearing for pastureland by commercial and speculative interests‚ misguided government policies‚ inappropriate World Bank projects‚ and commercial exploitation

How Acid Rain Affects Organisms in Aquatic Biomes Through the advancement of technology‚ the issue of the air surrounding the earth might have been one of the most often matters to be brought up and discussed among scientists and engineers. Acid rain is one of the more serious environmental problems and it is closely related to the air pollution. Nowadays‚ it has affected large part of US‚ Europe and Canada. People start to be concerned about acid rain since it is getting worse in the passed

and family members. Keywords: dengue‚ geriatric‚ appetite‚ anorexia‚ weakness‚ absent fever Introduction: Dengue is caused by the Dengue Virus (den1-4)‚ which is a Flavivirus (RNA)‚ spread via the Aedes aegypti mosquito. It is prevalent in the tropical climate countries‚ as the environment is ideal for breeding mosquitoes. Approximately 100 million people are affected by dengue yearly‚ making it the leading cause of illness and death worldwide [1]. Its effects range from asymptomatic to death

Outline the relationship between climate and one or more biomes. Arctic tundra is a biome characterized by cold weather and low growing plants and shrubs and virtually no trees. They are found mainly in regions just below the Arctic ice caps‚ located at latitudes 55o to 70o North‚ across North America‚ Europe‚ Alaska‚ Canada and Siberia. They cover 20% of the earth’s surface. The summer season is short‚ where there are brief periods when the sun shines for almost 24 hours a day and temperatures

1.The average temperature contrast between winter and summer is greater for continental polar air than for maritime tropical air. Explain why. Maritime tropical air is very warm and humid because its source regions are tropical and subtropical seas. This air mass retains these properties year-round and is responsible for oppressive summer heat and humidity east of the Rocky Mountains. Dry continental polar air develops over the northern interior of North America. In winter‚ continental polar air

of communication in understanding the role of tropical rainforests in preventing climate change. The global atmosphere is undergoing rapid change‚ especially in terms of increasing average temperatures worldwide‚ and this is primarily attributed to human activity (Malhi & Wright‚ 2004). One important factor in this increasing temperature is the constant clearing and destruction of tropical rainforests. It is crucial that the importance of tropical rainforests‚ as global heat and water pumps‚
