Weather Wise Kids Question… Why is it Windier at the Tree Tops than the Ground?

News

WIND CAN DEFINITELY GET STRONGER THE HIGHER UP YOU GO

YOU MAY NOTICE THIS WHEN WATCHING THE TREES…  OR WHILE HIKING AT THE COUNTRYSIDE, WHERE IT CAN BE WINDIER AT THE TOP OF THE HILL.

OR MAYBE EVEN WHEN FLYING A KITE…  IF IT’S TOO CLOSE TO THE GROUND, IT MAY FALL.  BUT IF YOU GET THE KITE HIGH IN THE AIR, IT WILL BECOME STEADY AND FLY!

SO WHY IS THERE A DIFFERENCE?

WELL TO GET WIND…  IT’S THE AIR FLOW FROM A REGION OF HIGHER PRESSURE TO A REGION OF LOWER PRESSURE.

THE MOVING AIR IS THEN SLOWED DOWN BY THE FRICTION BETWEEN THE AIR AND ANY OBJECTS.

FOR EXAMPLE, BUILDINGS ON THE GROUND…   THIS CAUSES FRICTION….  THE AIR FLOW IS DISRUPTED…  AND THE AIR IS SLOWED.

THE OPPOSITE HAPPENS HIGHER UP….  WAY UP IN THE SKY… THERE’S LESS FRICTION.  THE AIR FLOWS FASTER AND STRONGER.

AND SPEAKING OF STRONG….  THE STRONGEST SURFACE WINDS EVER RECORDED HAPPENED ON MOUNT WASHINGTON IN NEW HAMPSHIRE….  WHERE THE WINDS PEAKED AT 231 MILES PER HOUR!!!!
