The state of Indiana is located in the northern part of the United States of America. Among petrol heads the state is mainly known for the Indianapolis 500 mile race, also known as the Indy 500. This race is held annually on the Sunday prior to Memorial Day and is among the best known motor sports races in the world. The landscape of Indiana is quite flat, on average located at an altitude of 230 meters above sea level. Indiana has three climate zones. The most northerly located part has a moderate continental climate. in the south a small zone can be found with a warm maritime climate (type Cfa according to the Köppen climate classification). However, the largest part of Indiana has a warm continental climate (type Dfa according to the Köppen climate classification). This climate is characterized by warm to very warm summers and winters in which snowfall and longer periods with subzero temperatures are not uncommon. In January, which is the coldest month average minimum temperatures are -10 degrees Celsius (14 degrees Fahrenheit). During the warmest month, which is July temperatures are around 30 degrees Celsius (86 degrees Fahrenheit) or even higher in the southern part of the state. In the northern part of Indiana the vegetation period lasts 155 days per year, in the south 185 days. About half of the annual snowfall is caused by ‘Lake effect snow’. During cooler atmospheric conditions when cold winds move across long expanses of warmer lake water, water vapor is picked up. The vapor freezes and is deposited in the form of snow.
