Weather Chart

Prior to this activity I thought that the weather would not change so drastically, and the temperature would stay relitivally the same.
The activity's objectives were to understand more about the weathers patterns during this time of the year, and Michigan's climate.
I learned from this activity that the weather is really unpredictable. It can vary greatly from day to day.

This connects to my topic because the weather effects the ocean currents. If the weather is bad and stormy, than the ocean will be really rocky.Water currents effect the climate conditions around the world by directly influencing weather patterns and ocean currents.

Ocean currents

Ocean currents are movements of oceanic water continously. The ocean currents are either hot or cold like rivers that move across the ocean at a steady rate. They are formed from the planet rotation, temperature changes in the ocean and differences in the gravitation of the moon. Ocean currents are able to flow thousands of kilometers and are a key element in determaining the climate of an enviornment, especially those areas closer to the ocean ridge. An example of a popular ocean current is the gulf stream. The ocean currents are measured in sverdrups.
Write about where and why your climate issue happens:
Ocean currents happen in the ocean. Ocean currents are created due to moving winds and waters in the ocean constantally moving. How they move influences climate and living conditions for plants and animals, even on land.
What is needed for the weather conditions to occur:
In order for this to occur there has to be wind involved to create the ocean currents.

The ocean currents affected by wind, the water's salinity and heat content, bottom topography, and the earth's rotation.

What happens to the environment and the people:
When ocean currents take place it effects sea life, and the people on land. Education is important to reducing the costs of shipping since that reduces fuel costs. In the sail-ship era knowledge was even more essential. A good example of this is the Agulhas current, which long prevented Portuguese sailors from reaching India. Even today, the round-the-world sailing competitors employ surface currents to their benefit.
Write about where and why your climate issue happens. :
Ocean currents are caused by wind.
What is needed for the weather conditions to occur:
In order for ocean currents to occur there must be wind.
What happens to the environment and the people :
Ocean currents greatly affect animals on land and in the ocean. Ocean currents are also very important in the dispersal of many life forms. A dramatic example is the life-cycle of the eel.
How are they predicted:
Ocean currents are predicted by patterns that the ocean currents flow and tonographic technology.

How are warnings issued: Warnings for natural disastors due to ocean currents are issued by the national weather service pacific tsunami warning center or other centers like these.
