This calculator demonstrates the mathematics of determining the geostrophic wind speed at a variety of latitudes, temperatures, and heights. The calculator is preformatted for a height of 11 km (the "average" height of the troposphere), a latitude of 45^{o} north, and an average temperature of 0^{o} Celsius (converted to degrees Kelvin, K = C +273.15). The mathematics of this calculation are shown in the graphic at right. The geostrophic wind is a theoretical wind speed that results from a balance between the Coriolis force and the pressuregradient force, concepts explored in greater detail in later readings.
