Relationship Between The UV Index And Equatics

a much greater annual temperature range than City B. The most likely explanation for this fact is

Meaning that at latitudinal points closer to the poles there is less bio-diversification, and when approaching close to the equator and tropics the bio-diversification increases. The first theory on why this occurs is that in the tropics the species evolutionary clock ticks faster, increasing the chance of genetic mutations. Another theory is that in the area of the tropics the species there are more finicky because of the consistent temperature creating a low thermal tolerance creating insuperable barriers. Another theory is that the age of the tropics, rainforests, are old in comparison to the barren ice covered lands of the polar regions, creating an ideal place for life to

The first is the maritime vs. continental relationships Brownsville is near a few water sources like the Rio Grande River and the Gulf of Mexico. Land-sea breezes wind system the air flows from the sea toward the land, so high to a low pressure zone. It can have an impact on the temperature and airflow direction. The second is the air mass circulation and Brownsville is located near the tropic of Cancer. Brownsville latitude is 25.9303° N, 97.4844° W, so it’s within the Subtropical high pressure system. This makes it for hot and dry weather. The next component is the latitude, so it affects the climate and the range of sun insolation Brownsville receives because of its latitude. Then the seasonality is also an important variable in the distribution of climate for two reason related to the sun angle. The number of hours of sunlight in a day Brownsville receives. The second is insolation and temperature can be important between the summer and winter seasons.

The stratosphere absorbs the UV radiations. The troposphere is the lowest part of Earth’s atmosphere.

According to Hess, “The angle at which solar rays hit Earth’s surface varies with latitude. The higher the angle, the more concentrated the energy and therefore the more effective the heating” (2011, p. 80). St. Louis, Missouri is located at 38° 39' N, 90°W, which puts it north of the Tropic of Cancer. The angle of incidence is between 10 and 40 degrees, which causes cooler temperatures since the insolation is spread out over a large area.

According to the United States Environmental Protection Agency (2010), ultraviolet (UV) rays are remarkably damaging to the skin without the proper protection. The National Weather Service and the EPA have developed the UV Index, a tool that predicts the level of UV radiation and indicates the risk, numerically. It is scale in which 0-2 indicates low risk of danger from sun rays, 3-5 indicates moderate risk, 6-7 indicates high risk, 8-10 indicates very high risk, and 11+ indicates extreme risk of harm. There are a considerable number of factors that influence an ultraviolet level, including stratospheric ozone layer, time of day, time of year, latitude, altitude, weather

Ultraviolet radiation is found in sunlight. It is classified into UVA and UVB. Both of these contribute to premature aging in the skin and can be avoided by the use of protective clothing, hats and sunscreen. The first sign that the skin has been affected is a sunburned or even tanned skin. However, there is also damage that cannot be seen. The DNA in the skin cells is also damaged, so the cells no longer have their protective function.

There is significant variance in day to day temperature, especially during the winters. Moreover, the temperatures at the night are substantially different from the day due to proximity to water.

e following image (Figure 1) represents a map of the world on which the UV-light Index has been superimposed. e latitudes are shown on the left (latitude helps de ne a location on Earth, speci cally how far north or south of the equator a site is).

Even people who don't spend hours at a time in intense sunlight, are exposed to UV radiation, including on overcast days. This is difficult to believe given that we don't

The Troposphere is the lowest layer from Earth of Earth’s atmosphere. In the troposphere is where all weather takes place. The second layer is the Stratosphere which has warmer layers than most of the atmosphere. The Mesosphere is the third layer of Earth’s atmosphere. In this layer temperature decreases with altitude. It also includes the coldest places on Earth. The next layer is the Ozone. In the Ozone layer gases and chemicals protect us from harmful Uv radiation from the sun. The last and final layer of the atmosphere is the Thermosphere. In the Thermosphere Uv radiation is captured by the sun and warms up this layer. This is the warmest layer of all of Earth’s atmosphere. Also in this layer radio waves are refracted due to the solar radiation interfering with

The higher your altitude, the less protective atmosphere above you to protect against UV light. This means you get a higher rate of exposure than someone living at sea level.

The effect of the potential increase in urban albedo on IRF is also dependent on the urban areas can be enhanced. In Figure 2 we reported both the responsiveness (indicated by the color bar) and the area of the cities (see also table 1) of the 125 most populous cities.

As shortwave radiation from the sun reaches the Earth, about eighteen percent of this radiation is absorbed into the atmosphere. The remaining energy is reflected back or absorbed by the Earth. This reflection is known as albedo. Objects with a higher reflectivity have a higher albedo and vice versa. Similar to the sun, the Earth and its atmosphere also emit radiation. Because the Earth is much cooler than the sun, this radiation is in the form of longwave radiation (Nature of Radiation Lecture). Although, not all of this radiation exits the Earth’s atmosphere, some of this radiation is absorbed back into the Earth. This is known as the greenhouse effect. Greenhouse gasses absorb radiation. This radiation is emitted by greenhouse gasses and absorbed into the Earth, which in turn, heats up the surface of the Earth. By increasing the amount of greenhouse gasses in the atmosphere, the temperature will continue to rise. In the polar regions of
