There are several factors that influence the climate or prevailing weather conditions for any given location on Earth. The most important factor is the latitude of the location because that affects the amount of solar radiation received throughout the year. Other factors include its distance from a body of water (its moisture source), elevation and local topography. In this 6 to 10 day unit plan, ... Full description.

Our atmosphere is warmed by shortwave radiation received from the Sun. Some of the energy is reflected back to space depending on cloud cover and the surface characteristics of Earth. Some of the energy is absorbed by the surface, then re-emitted back to space as longwave radiation. As this occurs, clouds and atmospheric gases can reflect, absorb and re-emit this energy -- the so-called greenhouse ... Full description.

Students often hear that winters were colder or had more snow in the past. This activity will help them to determine if this is a true or accurate statement for their location. Students will access historic weather information from NOAA and NASA internet resources. They will determine changes in average temperatures, precipitation and cloud cover over time from data and relate global changes to local ... Full description.

In this lesson, students use the Live Access Server to research possible trends present in atmospheric and oceanic conditions which may affect future hurricane frequency and or intensity. Students write a summary discussing what steps should be taken, if any, to mitigate the danger of future hurricanes in a selected area. Detailed Procedure and Materials, Vocabulary linked to an On-line glossary, ... Full description.

Water is one of Earth's most unique and valuable resources. Thus, the distribution of water on Earth is a very important factor in the evaluation of global climate and its impact on life. In this lesson, students will use historical satellite data to examine precipitable water -- a measure of the water available in the atmosphere from evaporation (in the form of water vapor). They will then compare ... Full description.

Students will make predictions by linking current scientific satellite data to concerns about global climate change. Using maps of sea surface temperature (SST) and ocean surface winds, students will learn how differential heating of Earth results in circulation patterns in the atmosphere and oceans that globally distribute the heat. Students will learn the relationship between the rotation of Earth ... Full description.

Back in the days of Christopher Columbus, voyages made across bodies of water were dependent upon winds and currents to drive the sailing ships. Thus good navigation routes were often determined by prevailing weather conditions such as the Trade Winds, and then discovered by explorers. In this lesson, students will explore the wind climatology for the Atlantic Ocean basin (as determined by satellite ... Full description.

Many claims have been made about the evidence for or against global warming, yet whether the interpretation of the data points leans towards fact or fiction, a more descriptive term to use is global climate change. The most hard-hit area where global climate change is apparent is within the Arctic Circle. In this lesson, students will explore data from the Arctic, develop relationships between parameters ... Full description.

In recent years more and more attention has been paid to the Earth's climate and how it is evolving. When studying hurricanes it is important to understand that, for a hurricane to grow, warm water is an absolute necessity. So if the Earth continues to warm, what does that mean for hurricanes and their intensity? In this lesson, the student will look at past hurricane data by researching the intensity ... Full description.

El Nino and La Nina are important temperature fluctuations in surface waters of the tropical Pacific Ocean. In this lesson, students will create maps and line graphs of data to compare the effects of El Nino and La Nina at two different longitudinal locations, but at the same latitude, using sea surface temperature and precipitation from real satellite data.
