The Country of Chile extends approximately 2,500 miles from the bottom of South America to the Tropic of Capricorn. This vast area gives Chile multiple climates due to its extension from the tropics to the Antarctic. The Pacific Ocean with the Humboldt Current and the Andes also influence Chile's climate. The climate can be divided into three main categories: subtropical deserts, temperate rainforest and tundra. The main catastrophic natural disaster is occasionally earthquakes or tsunamis. The weather generally cools as you move south through the country. The Pacific Ocean keeps temperatures in a moderate range so that there are no dramatic changes in temperature between seasons. Chile's subtropical deserts are found mainly in the northern areas of the country. The land is known for its aridity. This area is home to the Atacama Desert, which sees little to no rain most years and is known as the driest desert in the world. In the desert there are extreme changes in temperature from day to night. The daytime temperature typically ranges from 30-50 degrees Celsius, and at night drops to -15 degrees Celsius. A range called the "Little North" is a transition zone between the northern deserts and the temperate rainforest zone. This is a semi-arid region with irregular rainfall, but most of the humidity is due to fogs caused by the Humboldt Current. The average temperature for this region is 14.7 degrees Celsius. The central region hosts a Mediterranean and temperate rainforest climate. This area has the most moderate climate conditions and more precipitation, especially rain, than other regions. This area has the most defined seasons. The cold season is from May to September, and the hot season is from October...... middle of document ......le, 2003. p111-115.
