Why Is a Weather Buoy Left Alone in the Ocean?

What Crafty Clover says in this video

Intro

Hey there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why is a weather buoy left alone in the ocean?

The Big Idea

A weather buoy is a floating robot weather station. It sits in the ocean for months, measuring wind, waves, temperature, and air pressure. Then it radios the numbers to satellites. It never needs a sandwich!

Step 1

Step one: sensors feel the wind and waves. Tools on the buoy measure wind speed, wave height, air pressure, and temperature, all day and all night.

Step 2

Step two: a radio talks to a satellite. The buoy stores its numbers in a little computer. Then its radio sends them up to a satellite, which passes them down to land.

Step 3

Step three: forecasters get the report. Weather forecasters use the numbers to warn ships and coastal towns about storms. Meanwhile the buoy keeps on bobbing, ready for the next reading.

A Closer Look

Let's take a closer look at a weather buoy! The float is the big, bobbing body that keeps everything on top of the water. The mast sensors up high measure wind and air. And the anchor line is a cable that can hold the buoy in place on the sea floor.

Quick Facts

Quick facts! A buoy can keep watch for months with nobody on board. Some buoys are anchored to the sea floor, and others drift with currents. A missing buoy leaves a hole in the storm map. Boaters should give buoys room, and never climb on them or tie up to them.

Think Like a Scientist

Now, think like a scientist! Why leave a machine out there instead of a ship? Then, what two jobs does the radio do? Try this: with a grown-up, check a weather map and see where the buoys are.

Outro

A buoy is a patient weather watcher with no crew. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
