<p> Earth Systems Review Unit 3 – Climate and Weather</p><p>Miscellaneous</p><p>Current, short-term variations in the atmosphere are referred to as this.</p><p>An extended period of well below-normal rainfall.</p><p>The number of years it takes before an area’s weather can be classified as climate.</p><p>Where would a heat island most likely be located?</p><p>Climate data include what three things?</p><p>Storms</p><p>A source of moisture, lifting air mass, and an unstable atmosphere are all conditions that must exist to produce this.</p><p>Friction between updrafts and downdrafts in a cumulonimbus cloud forms this.</p><p>The stage of a storm when equal amounts of updrafts and downdrafts exist. </p><p>These are often associated with supercells.</p><p>The type of storm that forms because of unequal heating within one air mass.</p><p>Cyclones</p><p>This area of a hurricane has the strongest winds and densest clouds.</p><p>The two conditions that exist in the eye of the storm.</p><p>A mound of water driven toward coastal areas by hurricane winds.</p><p>A storm over the ocean with winds speeds over 75 km/h can be classified as this.</p><p>This scale is used to measure hurricane strength. Climate Regions</p><p>This zone has constant high temperatures.</p><p>In this climate type, summer and winter temperatures can be extreme.</p><p>Precipitation in this zone is low and vegetation is scarce.</p><p>Region that is a tundra with cold temperatures and no trees</p><p>This climate type can be divided into two subtypes: humid and dry summer</p><p>Climate Change</p><p>Unusually cold climate conditions correspond to period of low sunspot activity known as this.</p><p>What natural phenomena will eventually cause the Northern Hemisphere to experience summer during today’s current winter?</p><p>Period when Earth’s surface was covered by vast sheets of ice.</p><p>Warm ocean current that develops off the west coast of S. America.</p><p>Short period of climatic change caused by variations in daylight, temperature and weather patterns.</p><p>Short Answer – What human activities contribute to changing Earth’s climate, and what can be done to minimize the impact?</p>
