Final answer:

Global atmospheric circulation, wind patterns, rainfall, and ocean currents are influenced by factors such as temperature, pressure, and the Earth's rotation. Local and seasonal variations can be caused by proximity to water, topography, and mountain ranges. The most important climatic factors in determining the location of biomes are temperature, precipitation, and sunlight.

Step-by-step explanation:

Global atmospheric circulation refers to the movement of air around the Earth's surface. It is driven by several factors including temperature, pressure, and the Earth's rotation. There are three main wind patterns: the trade winds, the prevailing westerlies, and the polar easterlies. These wind patterns are influenced by the Earth's rotation and the distribution of land and water.

Global atmospheric circulation also impacts rainfall patterns. Areas near the equator receive more rainfall due to the convergence of warm, moist air. As air rises, it cools, leading to condensation and precipitation. In contrast, areas near the poles receive less rainfall because the air is cooler and holds less moisture.

Ocean currents are driven by a combination of wind patterns, temperature, and the Earth's rotation. They play a crucial role in transporting heat around the globe and influencing the climate of different regions. For example, the Gulf Stream carries warm water from the Gulf of Mexico to the North Atlantic, moderating temperatures in Europe.

Local and seasonal variations in these patterns can be caused by factors such as the proximity to large bodies of water, topography, and the presence of mountain ranges. For example, coastal areas may experience sea breezes due to the temperature difference between land and water. Mountain ranges can create barriers that prevent the movement of air and influence precipitation patterns on both sides of the mountains.

The most important climatic factors in determining the location of biomes include temperature, precipitation, and sunlight. Different biomes are characterized by unique combinations of these factors. For example, tropical rainforests are found in regions with high temperatures, high precipitation, and abundant sunlight, while deserts are found in regions with high temperatures, low precipitation, and strong sunlight.
