Latitude is a measure of the distance you are located from the equator. We can see these lines as imaginary horizontal lines that go across the earth on maps and is used along with longitude as a reference point to determine location. The tilt of the earth affects the seasons we experience throughout the year. Why do we care? The latitude and tilt of the earth are key factors which determine the climate at a particular location. The definition of latitude is the angular (Earth is a sphere) distance north or south from the earth’s equator measured through 90 degrees. Lines of latitude form circles around the earth, with 0 degrees latitude being at the equator and 90° latitude representing the poles. For example, Miami, Florida, is located at approximately 26 degrees North latitude while New York, New York, is located at approximately 41 degrees North latitude. Latitude is an important factor in determining what type of climate a location will have. For example, we can expect Miami’s climate to be much warmer than that of New York since it is at a lower latitude and is located closer to the equator. Locations at lower latitudes receive stronger and more direct sunlight than locations near the poles. Energy from the sun is the main driving force in the atmosphere. The tilt of the Earth and the direct or indirect rays of the Sun are what drive the climate of our planet! How does this all relate to climate and why we need to learn this stuff? Actually, Seasonal patterns effect whether we live or die! Seasonal extremes of hot and cold temperatures bring on influenza, and allergies. Latitude is associated with heat-related deaths. People who live in more southern cities are more vulnerable during events of colder temperatures, while people in more northern cities are more vulnerable during events of warmer temperatures. Mid-latitude cities, like North Carolina, tend to experience greater summer climate differences. These cities are expected to experience the greatest increase in summertime heat-related deaths as a result of climate change. Influenza or flu activity peaks during the winter months in the U.S., particularly during the month of February. Researchers in New York City have developed a new weather modeling technique that factors in periods of dry weather, and therefore can predict the timing and severity of seasonal influenza outbreaks up to eight weeks out. Flu forecasts could alert residents to take extra precaution by getting vaccinated, and public health professionals to ensure sufficient stockpiles of vaccines and antiviral drugs. Knowing all we can about how the direct and indirect rays of the Sun effect us where we live can save our lives.... Humans are effected by sunlight. In Alaska and up into far northern latitudes where the Sun's rays are indirect and daylight hours occur only half of the year, people struggle with depression and illness. Scientists are trying to develop ways for people to feel better if they live in the far north or far south parts of the globe. Phosphorous lights in rooms and businesses that are brighter are used to help people feel better effects from light energy. The scientific study of direct and indirect light have helped humans adapt to extreme situations and keep their good health.

Mrs. TaylorI love science! Everything about the world is interesting and never boring. I love to study plants, animals, insects, and people. My favorite subjects are my students who are the most unique organisms on the planet! Categories |
