Dhofar Region, Oman. Much of Oman is desert, but the Arabian Sea coast in the Dhofar region represents a startling difference in climate. This coastal region catches the monsoon rains, or khareef, during the summer months. Drenching rains fall primarily on the mountainous ridge that separates the lush, fertile areas along the coast from the arid interior, recharging streams, waterfalls and springs that provide plentiful water supplies in the fertile lowlands for the remainder of the year.

Girls dressed in “Hanfu”, or Han clothing, prepare for an event to mark the traditional Qixi festival, the Chinese equivalent of Valentine's Day, at a park in Beijing, China, August 7, 2019.
