The Global Precipitation Measurement or GPM center observatory satellite went above Tropical Cyclone Ula when it was shaping in the South Pacific Ocean north of Samoa on December 29, 2015 at 1321 UTC. A precipitation investigation was performed utilizing information gathered around then by GPM’s Microwave Imager (GMI) and Dual Frequency Precipitation Radar (DPR) instruments.
Information from GMI were utilized to figure that rain was falling at a rate of more than 83.6 mm for every in a feeder band (of electrical storms) upper east of the low weight zone’s middle. At NASA’s Goddard Space Flight Center in Greenbelt, Maryland, information from GPM’s DPR Ku band radar were utilized to make a 3-D structure of precipitation inside of the shaping tropical tornado. Some tempest top statures in the 3-D radar cross segment indicated storm top statures of more than 15 km At 0900 GMT on Dec. 31, Ula’s greatest managed winds were almost 55 hitches and reinforcing. Ula is relied upon to top at 80 hitches on January 2.
Ula was focused close to 15.5 south scope and 169.0 west longitude, around 122 nautical miles southeast of Pago, American Samoa. Ula was moving toward the west-southwest at 6 hitches. The tempest is additionally creating high oceans with wave statures to 22 feet, so Pago and Fiji can expect unpleasant surf and risky waterfront conditions. Ula’s inside is conjecture to stay south of Fiji.
Be that as it may, Fiji will feel the impacts of unpleasant surf, solid winds, substantial precipitation and the potential for inland flooding. On Dec. 31, the Fiji Meteorological Service issued a substantial downpour cautioning for eastern and northern Viti Levu, Vanua Levu, Taveuni And Nearby Smaller Islands, Yasawa And Mamanuca Group. NOAA’s GOES-West satellite caught a picture on Dec. 31 at 1200 UTC that demonstrated a little eye had framed in Tropical Cyclone Ula when it was only south of Pago in the Southern Pacific Ocean.
The picture likewise demonstrated a thick band of storms around the focal point of course. The picture was made by the NASA/NOAA GOES Project at NASA Goddard. The Joint Typhoon Warning Center noticed that Ula is following westbound along the northern edge of a fortifying sub tropical edge, situated toward the south.
That edge will remain the fundamental controlling instrument for the tempest throughout the following couple of days. Ula is relied upon to keep heightening throughout the following two days until it keeps running into a drawing closer center scope trough of low weight, which will expand vertical wind shear and start debilitating the tempest.
