NASA checks out Hurricane Sergio's cloud temperature 9 October 2018 At the time Aqua passed overhead, coldest cloud top temperatures in thunderstorms circled the eye and appeared in fragmented bands of thunderstorms north and south of the center. Those temperatures were as cold as or colder than minus 63 degrees Fahrenheit (minus 53 degrees Celsius). The exception was on the western side of the storm , where cloud top temperatures were warming, meaning they were not getting as high in the atmosphere. Despite the slow weakening the hurricane still has a large but well-defined inner-core in the low and mid-levels. The National Hurricane Center noted at 11 a.m. EDT (1500 UTC), the center of Hurricane Sergio NASA's Aqua satellite provided an infrared picture of was located near latitude 16.6 degrees north and Hurricane Sergio's cloud top temperatures from Oct. 9, longitude 127.4 degrees west.

Infrared data showed cloud top temperatures were getting NHC noted that there are no coastal watches or warmer on the western half of the storm, indicating warnings in effect, but interests in Baja California the uplift of air in storms had weakened. Sur should monitor the progress of Sergio. The Atmospheric Infrared Sounder or AIRS instrument aboard NASA's Aqua satellite passed Provided by NASA's Goddard Space Flight Center over Hurricane Sergio on Oct. 9 at 6:17 a.m. EDT (1017 UTC). AIRS uses infrared light and infrared light provides scientists with temperature data and that's important when trying to understand how strong storms can be. The higher the cloud tops, the colder and the stronger they are. So infrared light as that gathered by the AIRS instrument can identify the strongest areas of a tropical cyclone. 1 / 2 APA citation: NASA checks out Hurricane Sergio's cloud temperature (2018, October 9) retrieved 24 September 2021 from https://phys.org/news/2018-10-nasa-hurricane-sergio-cloud-temperature.html This document is subject to copyright.

HURRICANE SERGIO (EP212018) 29 September–12 October 2018
NATIONAL HURRICANE CENTER TROPICAL CYCLONE REPORT HURRICANE SERGIO (EP212018) 29 September–12 October 2018 Eric S. Blake National Hurricane Center 26 February 2019 GOES-16 INFRARED IMAGE OF SERGIO NEAR PEAK INTENSITY AT 0600 UTC 4 OCTOBER 2018. Sergio was a long-lasting tropical cyclone that took a sinuous track over the eastern Pacific Ocean. It peaked as a category 4 hurricane (on the Saffir-Simpson Hurricane Wind Scale) before weakening over cooler waters and turning back toward Mexico. While it eventually made landfall in Baja California Sur as a low-end tropical storm, the overall impacts were not severe. Hurricane Sergio 2 Hurricane Sergio 29 SEPTEMBER–12 OCTOBER 2018 SYNOPTIC HISTORY Sergio could have originated from a tropical wave that left the coast of west Africa on 13 September. This feature lost definition over the tropical Atlantic Ocean during the next few days, with little signature in either the wind or convective fields. While extrapolation suggests the wave could have led to Sergio’s formation, the degradation in the signal makes it impossible to conclusively link the wave to the first clear precursor system that was noted over northwestern South America on 24 September. The disturbance produced increased convection as it passed over Central America during the next two days. The thunderstorm pattern consolidated on 27 September over the eastern Pacific waters, although NOAA Hurricane Hunter aircraft data showed only a weak surface trough. Persistent convection started the next day near the trough, which led to an increase in winds and low-level organization. However, while the NOAA aircraft showed that tropical-storm-force winds were now present, the large disturbance lacked a well- defined center.

NASA Sees Powerful Storms Circling Major Hurricane Sergio's Eye 3 October 2018
NASA sees powerful storms circling major Hurricane Sergio's eye 3 October 2018 cloud top temperatures as cold as minus 80 degrees Fahrenheit (minus 62.2 Celsius). NASA research has shown that cloud tops with temperatures that cold were high in the troposphere and have the ability to generate heavy rain. The National Hurricane Center or NHC noted at 5 a.m. EDT (0900 UTC), the center of Hurricane Sergio was located near latitude 12.3 degrees north and longitude 116.7 degrees west. Sergio is moving toward the west-northwest near 12 mph (19 kph). Fortunately, Sergio is far from land areas. It is about 855 miles (1,380 km) south-southwest of the southern tip of Baja California, Mexico. A west-northwestward to northwestward motion at a slightly slower forward speed is expected over the next few days. Maximum sustained winds are near 115 mph (185 kph) with higher gusts. Sergio is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. At 2:30 a.m. EDT (0630 UTC) on Oct. 3, 2018 the Some strengthening is forecast during the next day MODIS instrument that flies aboard NASA's Aqua or so, with weakening expected to begin by Friday. satellite gathered infrared data on Hurricane Sergio. Strongest thunderstorms circled the center where cloud top temperatures were as cold as (yellow) minus 80 degrees Fahrenheit (minus 62.2 Celsius).

An upper-level cold trough moves in behind the system with cooler temperatures and a chance of rain. The remnants of Rosa have moved out of the southwest leaving between 1-3 inches of rain across the region. Unseasonably cool temperatures and a chance of rain remain as these systems move through the region. Isolated showers and seasonal temperatures continue across Central Mexico into next week. To the north, Mostly dry conditions are expected following Rosa’s departure Market Alerts with cooler temperatures due to cold fronts passing to the north. Long range Bell Peppers (Eastern): Supplies are forecasts show another Hurricane (Sergio) possibly taking a similar path as Rosa good in Midwest and southeast is late next week. Florida will see mostly dry conditions under a strong high pressure getting more supply. into the weekend. Berries (Blackberries): Domestic supplies remain very limited in all California loading locations. Berries (Blueberries): Supplies remain very limited and market prices are higher. Berries (Strawberries): The rain has come! Harvest will be effected more down south, but we may see some limited supplies across the board. Quality may be a challenge. Cucumbers (Eastern): Light supplies, market is a little lower. Eggplant (Eastern): Supplies getting better, Quality excellent. Potatoes: Heavy rains in the Wisconsin area will cause harvest interruptions with rain in the forecast for the next 7 to 10 days Colorado harvest could be interrupted later this week with rains from tropical storm Rosa.

Tropical Cyclone Report Hurricane Sergio (EP212006) 13-20 November 2006
Tropical Cyclone Report Hurricane Sergio (EP212006) 13-20 November 2006 Richard J. Pasch and David P. Roberts National Hurricane Center 29 November 2006 Sergio was the strongest eastern North Pacific hurricane for so late in the season, and it was also the longest-lived November tropical cyclone on record for that basin. Since it was always embedded in weak steering currents, this tropical cyclone did not move very far during its lifetime. There was no direct impact on land. a. Synoptic History Sergio appears to have been spawned by a tropical wave that crossed southern Central America and entered the eastern North Pacific on 7 November. An area of cloudiness and showers associated with the wave moved slowly westward to the south of Central America and eastern Mexico over the next several days. Showers and thunderstorms became more concentrated by 12 November over an area centered roughly 350 n mi to the south of Acapulco, Mexico, and Dvorak classifications were initiated on the disturbance. By 1800 UTC 13 November, when the system was a little over 400 n mi to the south of Manzanillo, Mexico, it had acquired enough surface circulation and organized deep convection to be designated as a tropical depression. The “best track” chart of the tropical cyclone’s path is given in Fig. 1, with the wind and pressure histories shown in Figs. 2 and 3, respectively. The best track positions and intensities are listed in Table 1. Initially the cyclone was moving northwestward, but it soon stalled while strengthening into a tropical storm on 14 November.

FRANKLIN,RICHARD D. KNABB,MICHELLE M. MAINELLI,JAMIE R. RHOME, AND STACY R. STEWART Tropical Prediction Center/National Hurricane Center, NOAA/NWS/NCEP, Miami, Florida (Manuscript received 20 December 2007, in final form 20 May 2008) ABSTRACT The hurricane season of 2006 in the eastern North Pacific basin is summarized, and the individual tropical cyclones are described. Also, the official track and intensity forecasts of these cyclones are verified and evaluated. The 2006 eastern North Pacific season was an active one, in which 18 tropical storms formed. Of these, 10 became hurricanes and 5 became major hurricanes. A total of 2 hurricanes and 1 tropical depres- sion made landfall in Mexico, causing 13 direct deaths in that country along with significant property damage. On average, the official track forecasts in the eastern Pacific for 2006 were quite skillful. No appreciable improvement in mean intensity forecasts was noted, however. 1.
