Give a brief description of the surface currents in Earth’s
oceans.
•There are five main gyres in Earth’s oceans, caused by prevailing
winds.
•The two gyres in the Northern Hemisphere rotate clockwise.
•The three Southern Hemisphere gyres rotate counter-clockwise.
•The currents of the oceans are caused by a combination of these
gyre movements.
•Warm and cold currents have a huge effect on the Earth’s climate.

What is the major importance of ocean surface currents?
Ocean surface currents regulate the Earth’s climate.
What causes surface currents and what causes deep-ocean
currents?
Wind causes surface currents and water density differences
cause deep-ocean currents.
Announcements
Inconvenience Yourself Day is
an opportunity to focus on
inconveniencing ourselves
instead of inconveniencing
others. It is also a day to
recognize and acknowledge
those who inconvenience
themselves for others.
Acknowledgment can be verbal,
a note, or some small token of
appreciation.
Happy Inconvenience Yourself Day!
Announcements
I will inconvenience myself
and be available after
school today until 5:15.

Recent Events in Science
Weather Extremes Provoked by Trapping of
Giant Waves in the Atmosphere
The world has suffered from severe
regional weather extremes in recent
years, such as the heat wave in the
United States in 2011 or the one in Russia
2010 coinciding with the unprecedented
Pakistan flood. Behind these devastating
individual events there is a common
physical cause, propose scientists of the
Potsdam Institute for Climate Impact
Research (PIK). The study will be
published this week in the Proceedings
of the National Academy of Sciences and
suggests that man-made climate change
repeatedly disturbs the patterns of
atmospheric flow around the globe's
Northern hemisphere through a subtle
resonance mechanism.
