The climate of Oklahoma (United States of America)
The state of Oklahoma is located centrally in the southern part of the United States and mainly has a hilly landscape. Several mountains can be found in the northwestern part of the state; the highest point in the state is the peak of Black Mesa with an altitude of 1,516 meters. A large variety in landscapes can be found in the state such as forests, rocky canyons, grasslands and the characteristic Glass Mountains. The western part of Oklahoma has a warm continental climate, the eastern part has a warm maritime climate. the climate types here are very favorable to tornadoes and thunderstorms. When warm and cold air collide heavy thunderstorms may form. When this occurs so called super cells may form, these cells may cause twisters. On average 54 tornadoes per year can be recorded in Oklahoma. Several storm research institutes are based in Oklahoma such as the Storm Prediction Center. Summers in Oklahoma are fairly long (4 months) and warm. During the warmest months average maximum temperatures are 30-35 degrees Celsius (86-95 degrees Fahrenheit). Heat waves with temperatures exceeding 40 degrees Celsius (104 degrees Fahrenheit) may occur in the entire state. During fall precipitation figures are slightly higher and the state gets fewer hours of sunshine. Winter starts at the end of November and is fairly mild. Subzero temperatures during the day are uncommon. During the night temperatures may drop a few degrees below freezing point. However, when you travel further to the northwest the chances of low temperatures and snow increase.
