A 48 hour dust storm on March 1 and 2, 2003 is responsible for a very large dust transport over the Atlantic on March 2 through March 6, 2003. This animation starts with a global view of the world and zooms into the storm area.

In this video segment adapted from KUAC, find out why the horizon in Alaska is sometimes shrouded in pollution and what it means for climate change in the Arctic.

"This undergraduate class is designed to introduce students to the physics that govern the circulation of the ocean and atmosphere. The focus of the course is on the processes that control the climate of the planet.AcknowledgmentsProf. Ferrari wishes to acknowledge that this course was originally designed and taught by Prof. John Marshall."

What to expect from the parent groups organized to support school band programs.

A discussion of some of the opportunities available to former band students.

An introduction to a classification system for all musical instruments.

Concerns associated with developing orchestra programs in public schools, youth symphonies and higher education.

An introduction to the instruments of the modern Western orchestra.

For the families of students involved in a school band program, information about typical programs, band instruments, lessons, and practice.

For the families of interested students, an introduction to the world of music education in the U.S., with an emphasis on school band programs.

The laws of classical mechanics and thermodynamics are used to explore how the properties of fluids on a rotating Earth manifest themselves in, and help shape, the global patterns of atmospheric winds, ocean currents, and the climate of the Earth. Theoretical discussion focuses on the physical processes involved. Underlying mechanisms are illustrated through laboratory demonstrations, using a rotating table, and through analysis of atmospheric and oceanic data.

Typical expectations for students in school band programs and their families.

A summary of the type of events, both required and optional, in the typical school band program.

Some practical suggestions for parents dealing with stage fright in a young performer in a music-education setting.

The High Resolution Doppler Interferometer (HRDI) measures winds in both the stratosphere and mesosphere. The tropical winds in the stratosphere undergo a slow two year variation called the quasibianunual oscillation. This oscillation controls mixing throughout the stratosphere and HRDI has given us much detail on wind changes associated with this oscillation. The animation indicates the line of zero wind speed in the zonal tropical winds, the height at which the winds change from eastward to westward.

This game is suitable for play both within and outside of the classroom, and although designed for children ages 9-13, it offers a fun, learning opportunity for the entire family. In addition to being a game, it is an eye-catching poster showing continents, oceans and all of the major ocean currents. On the reverse, there are black and white educational activities designed to be reproduced directly from the poster for use in the classroom.

This simulation from the National Center for Atmospheric Research portrays annual patterns in water vapor and precipitation across the globe, illustrating general circulation patterns as well as seasonal and regional variation.

Weather is a constantly changing set of phenomena and easily observable. That's why weather also provides an excellent topic for scientific study. Even though meteorology includes some complex science, it is a wonderful example of how scientists make predictions based on measurements and observations. Each of the investigations in this section on Weather are led by an investigative question. It is important that students come to realize that scientists try to find out about the world by asking questions, predicting likely answers and conducting tests to see if their ideas are correct or not.

This video segment adapted from NOVA visualizes how Earth's rotation and uneven heating from the Sun cause prevailing winds and influence ocean surface currents. An animation and infrared satellite image illustrate the shape and direction of the Gulf Stream System in the Atlantic Ocean. Recommended for: Grades 6-12
