English: The image shows two cyclones in the Indian Ocean, Depression BOB 01 (later becoming Cyclonic Storm Viyaru) north of the equator and Moderate Tropical Storm Jamala south of the equator. Having two storms on either side of the equator allows us to see the Coriolis Effect in action by comparing the storms’ opposing angles of rotation.

While Jamala was forecasted to head southwest over water, BOB 01 was forecasted to move northwest and gain strength over the next few days before turning northeast and making landfall in Myanmar.
