The Indian summer monsoon, also known as the southwest monsoon, falls within the South Asian monsoon and is the strongest and perhaps best-known of the world’s monsoons. During summer months when the Asian landmass heats up, warm, moist air flows northward from the Indian Ocean towards the Himalayas, bringing abundant showers and thundershowers to India. The summer monsoon is a regular event that occurs every year and is responsible for roughly 80% of India’s annual rainfall. The summer monsoon typically starts in early June, peaks in July and August and winds down during September and early

The Pacific Northwest experienced a memorable series of storms in late Oct. 2021 as several low-pressure systems rolled in from the northeast Pacific Ocean. One of the systems was classified by meteorologists as a “bomb cyclone”, meaning that its central pressure (an indication of storm strength) had dropped particularly rapidly in a short time period. At its minimum pressure (highest strength), the system was reported by the National Weather Service to have had the lowest pressure of a system over the northeastern Pacific Ocean since reliable observations began in 1974. The system was notable

From late Sept. through early Oct. 2021, two powerful storms churned over the Pacific and Atlantic Oceans: Typhoon Mindulle, which peaked as a Category 5 storm, and Hurricane Sam, a Category 4 hurricane and one of the longest-lived hurricane-strength storms on record over the Atlantic Ocean. While neither storm posed a direct threat to land, Mindulle brushed by eastern Japan, leaving heavy rainfall accumulations in the area near Tokyo. Despite the fact that neither storm made landfall, the storms’ slow-motion tracks across warm ocean waters allows an opportunity to observe how the strong winds
