Known to sailors around the world as the doldrums, the Inter-Tropical Convergence Zone, (ITCZ, pronounced and sometimes referred to as the "itch"), is a belt around the Earth extending approximately five degrees north and south of the equator. Here, the prevailing trade winds of the northern hemisphere blow to the southwest and collide with the southern hemisphere's driving northeast trade winds. Because the air circulates in an upward direction, there is often little surface wind in the ITCZ.
A beach advisory leaves it up to users as to whether they wish to risk going into the water. In the case of a beach closure, the state and/or local government decides that water conditions are unsafe for swimmers and other users. There is no central database that provides information on beach closures and advisories in real time. The best way to find information on the current water quality of a particular beach is to plan ahead.
Adding a science service learning project to a standard inquiry-based environmental science curriculum helped fifth grade students learn climate science as they made connections between a real-world problem and their classroom learning. Students brainstormed, researched, and developed a project to address idling in the carpool lane at school. They collected and analyzed data, and used it to build a compelling anti-idling campaign for the school community.
