Earth-Sun Relationships determine the seasons around the world. Earth-Sun Relationships Weather conditions and climate are impacted by the annual. Earth/Sun Relationship, Weather, and Climate study guide by am includes 30 questions covering vocabulary, terms and more. Quizlet flashcards. Seasons, Weather, Climate, Extreme Weather Earth / Sun Relationships Earth's revolution and axial tilt change the amount of sunlight that parts of the Earth.

The high latitudes include the polar zones, which generally have very cold climates.

Elevation influences climate at all latitudes. The mid-latitude zone has a temperate climate. What is a temperate climate?

It is not an extreme climate, either hot or cold.

It is a mild climate with seasonal weather changes. Ocean currents also distribute energy; cold ocean currents circulate cold water into warmer water and warm currents move away from the Equator flowing into cooler water. Wind and water work together to affect weather, creating precipitation that both affects and is affected by temperature.

S NOAA definition is a 3-month average warming of at least 0. Large bodies of water are slower to heat and cool, so they help keep temperatures around them moderate.

Mountain ranges push air upward on the windward side, which cools and releases precipitation. After the precipitation is released, the air becomes warm and dry as it moves down the leeward side, resulting in a process that produces hot, dry areas with little precipitation called the rain shadow effect.

A biome is an ecological community defined by distinctive plant and animal groups. Tropical climates are found in or near the low latitudes.


TSI fluctuates slightly from day to day and week to week. Two different hypotheses have been proposed to test whether solar radiation can explain climate change. NASA The first hypothesis relies on the fact that in both the 11 year cycle and, in the longer term, the changes in solar energy are highest at ultraviolet short wavelengths. The short wavelength radiation is particularly effective in modifying ozone concentrations in the level of the atmosphere above where typical weather occurs.

According to this hypothesis, modifications in the ozone layer could in turn filter down to that level of the atmosphere where our weather is formed, potentially modifying clouds and temperatures there. Cosmic rays and clouds Cosmic rays were discovered unexpectedly in It is now known that most cosmic rays are atomic nuclei.

Most are hydrogen nuclei, some are helium nuclei, and the rest heavier elements. ChicagoNASA The second hypothesis relies on the fact that changes in solar activity also change the flow of small, charged, highly energetic particles known as cosmic rays that travel through the atmosphere toward Earth.

How Does the Sun Affect Our Climate?

The 11 year solar radiation cycle, as well as small increase in TSI sinceappear in some studies to be correlated with variations in cloud patterns. But, these changes in solar energy absorbed by the Earth appear to be far too small to explain the major changes in our climate.

Are other particles causing global cooling? During the last two decades, aerosol emissions increased in some countries and decreased in others.

Research shows that the impact of these particles on global average surface temperature over this time period is small.
