Seasonal Variation in Wind Strength

Obihiro experiences significant seasonal variation in wind strength. During the colder months, from October to March, the average wind speed is around 2.5 m/s (5.6 mph). This is due to the prevailing northerly winds that blow from the Sea of Okhotsk. In contrast, during the warmer months, from April to September, the average wind speed drops to around 2.0 m/s (4.5 mph). This is because the prevailing wind direction shifts to the south, bringing warmer and more humid air from the Pacific Ocean.

Diurnal Variation in Wind Strength

The wind speed in Obihiro also exhibits a diurnal variation. During the daytime, when the sun heats the land surface, the air near the ground becomes warmer and less dense than the air above it. This creates a vertical gradient in temperature and pressure, which results in upward-moving air currents. These currents then converge at higher altitudes, creating winds. As a result, the wind speed in Obihiro is typically strongest during the afternoon, with average speeds of around 3.0 m/s (6.7 mph). At night, when the land surface cools, the upward-moving air currents weaken, and the wind speed decreases. Consequently, the wind speed in Obihiro is typically weakest during the early morning hours, with average speeds of around 1.5 m/s (3.4 mph).
