Latitude and Longitude:
46.6500 degrees north, 91.5333 degrees west.
Climate:
Iowa is located in the humid continental zone where summers are warm, high 80's, cold winters, around 10 degrees F, and very wet springs.

How is climate different from weather?
Climate is weather conditions in an area over a long period of time. Weather is the state of the atmosphere at a given place and time.
What factors influence climate for a particular area?
.
-The distance from the sea (The coastal areas are cooler and wetter and when warm air from the inland areas meet cool air from the sea they form clouds)
-Ocean currents (can reduce or increase temperatures)
.
.
-Distance from the equator (The climate is cooler the farther you are from the equator)
-The El Nino (affect rainfall and wind patterns they also are blamed for droughts and floods in the countries around the pacific rim.)
.
.
-Human Activity (As the population of human grows we have to cut down trees which means that there is more carbon dioxide in the atmosphere.)
-Shape of the land (Mountains receive more rain than low areas.)
.
.
-Direction of prevailing winds (When the wind blows from the sea it brings rain to the coast and dry weather to the inland)
-Shape of the land (Mountains receive more rain than low areas.)

Thunderstorms occur when hot air rises into the troposphere meeting with a cold air and the masses become unbalanced creating thunderstorms. They key items needed to make thunderstorms is moisture, unstable air, and rising air. The rising air can come from different fronts, mountains, or sea breezes. Thunderstorms become more violent with the different warm and cold air temperatures that are mixed.

Types of Thunderstorms

The single-cell: the life cycle is limited to growth and collapse of a single upright current. The cloud grows to be mature and then begins to precipitate heavily, then decays as downward currents suffocate and make thinner than the original inflow. These thunderstorms are common in mid-summer and usually last an hour.
.
The multicell- is the most common and consist of one after the other separate upward currents that cause the systems overall strength, structure, and appearance. The currents may be close together causing the thunderstorms characteristics to stay the same over time or they could be widely spaced. causing the thunderstorm to cycle repeatedly through the stronger and weaker phases.
.
The super cell- is a special thunderstorm that can maintain an intense steady state for many hours. A highly organized movement with a continuous large upper current, the control over the surround atmosphere and make the size bigger. This impact makes this a fascinating, but dangerous cloud complex.

Temperature:-The highest temperature for Iowa City, Iowa for the month of April is 83 degrees Fahrenheit.
-The lowest temperature for Iowa City, Iowa for the month of April is 25 degrees Fahrenheit.
-The clouds in the sky for each day depend on the temperature. The clouds block the sun’s heat and traps other heat between the ground and the clouds. This is a result of different temperatures.
-When there is a high humidity, with warm temperatures, it creates a massive amount of warm and moist air rising in the atmosphere. When this occurs thunderstorms form really easy.

Humidity:
The humidity for April 30, 2014 is 79%
-The relative humidity (the ratio of the current absolute to the highest possible absolute humidity) depend on the current air temperature
-When the humidity is high the more easier it is for a thunderstorm to occur.

Dewpoint:
The dew point for April 30, 2014 is 38 degrees.
-Dew point determines whether or not it is going to rain or snow.
-Dew point is the temperature at which the water vapor condenses.
-The warmer the air the more moisture it can hold.
-The more moisture that is available the more heat that exist when the thunderstorm begins.

.Wind:
The wind speed for April 30, 2014 is 17 mph.
-The wind affects the weather by making the air colder or hotter.
-The wind affects thunderstorms in three main ways: gust front, downburst, and derecho
-Gust front is the leading edge of cool air rushing down and out from a thunderstorm. The reason is because the place where it is occurring is dry and is low in the atmosphere.
-Dry Downburst is associated with thunderstorms with little rain, and downburst are created with high amount of rainfall
-Derecho are associated with fast moving band thunderstorms.

Air Pressure:
The air pressure for April 30, 2014 is 29.77.
-Air pressure determine wind and weather.
Air pressure affects thunderstorms by changing wind and weather.

Clouds:
-The clouds affect the weather by the pattern that they have in the sky.
-Thunderstorms are actually produced from thunderstorms.

Plants:
-Iowa is located in between different habitats and climates.
-To the East and South of Iowa are humid and shrub forests
-The North of Iowa is cold with lots of evergreens and shrub forests
- Poison Ivy can be found all around Iowa
To the West is dry plains and deserts

Animal:
-Iowa has lots of plants and animals from theses areas
-Two examples that can be found anywhere in Iowa is Raccoon
-On the other hand the Pleistocene snail can only be found in some areas of the northeast of Iowa.

-The major river in Iowa include: Mississippi River, Des Moines River, Missouri River, Cedar River, and Iowa River
-The major lake is Lake Red Rock
