Presentation on Coriolis Effect

1. - Satyam Naidu

2.  Coriolis force is an inertial force (fictitious) that acts on
objects that are in motion relative to a rotating reference
frame.
 Deflection of an object due to the Coriolis force is called
the Coriolis effect.
 This is caused by the rotation of the rotating object.

3.  French physicist
Gustave Gaspard Coriolis (1792-1843).
 He published a paper in 1835 on the energy
yield of machines with rotating parts.
 Coriolis referred to this force as the
"compound centrifugal force“ and by 1920 it
has been named as "Coriolis force“.

6. Meteorology & Oceanography
 The most important impact of the Coriolis effect is in the
large-scale dynamics of the oceans and the atmosphere.
Ballistic Trajectories
 The Coriolis force is important in external ballistics for
calculating the trajectories of very long-range artillery shells.

7.  An object moving above the Earth in
northerly or southerly direction away
from the equator will have a greater
eastward velocity than the ground
underneath, and so will appear to be
deflected in relation to the rotation
off the Earth.
 Deflection is towards
Right  Northern Hemisphere
Left  Southern Hemisphere

9.  If a low-pressure area forms in the atmosphere, air tends to
flow in towards it, but is deflected perpendicular to its
velocity by the Coriolis force.
 The direction of movement of air around a low-pressure
area in
Northern Hemisphere  Counter Clockwise
Southern Hemisphere  Clockwise

12.  A Ocean Gyre in oceanography is any large system of
circulating ocean currents particularly those involved with
large wind movements formed due to the Coriolis Effect.
 The Coriolis effect deflects surface currents just like it
effects the wind. It deflects currents north of the equator
to the right and currents south of the equator to the left.

13.  The Coriolis effect causes Coriolis drift, both horizontally
and vertically.
 The deflection in
Northern hemisphere Right
Southern hemisphere Left
For eastward shots  Upwards Eotvos
For westward shots.  Downwards Effect
 Ballistic projectiles with long flight times it is a significant
factor in calculating the trajectory.
