  • Relation Between Tropical Easterly Waves, Convection, and Tropical Cyclogenesis: a Lagrangian Perspective
    AUGUST 2013 L E P P E R T E T A L . 2649 Relation between Tropical Easterly Waves, Convection, and Tropical Cyclogenesis: A Lagrangian Perspective KENNETH D. LEPPERT II AND DANIEL J. CECIL* University of Alabama in Huntsville, Huntsville, Alabama, WALTER A. PETERSEN NASA Goddard Space Flight Center/Wallops Flight Facility, Wallops Island, Virginia (Manuscript received 2 August 2012, in final form 3 January 2013) ABSTRACT In this study, a wave-following Lagrangian framework was used to examine the evolution of tropical easterly wave structure, circulation, and convection in the days leading up to and including tropical cyclo- genesis in the Atlantic and east Pacific basins. After easterly waves were separated into northerly, southerly, trough, and ridge phases using the National Centers for Environmental Prediction–National Center for Atmospheric Research reanalysis 700-hPa meridional wind, waves that developed a tropical cyclone [de- veloping waves (DWs)] and waves that never developed a cyclone [nondeveloping waves (NDWs)] were identified. Day zero (D0) was defined as the day on which a tropical depression was identified for DWs or the day the waves achieved maximum 850-hPa vorticity for NDWs. Both waves types were then traced from five days prior to D0 (D 2 5) through one day after D0. Results suggest that as genesis is approached for DWs, the coverage by convection and cold cloudiness (e.g., fractional coverage by infrared brightness temperatures #240 K) increases, while convective intensity (e.g., lightning flash rate) decreases. Therefore, the coverage by convection appears to be more important than the intensity of convection for tropical cyclogenesis.

  • ANNUAL SUMMARY Eastern North Pacific Hurricane Season of 2010
    VOLUME 140 MONTHLY WEATHER REVIEW SEPTEMBER 2012 ANNUAL SUMMARY Eastern North Pacific Hurricane Season of 2010 STACY R. STEWART AND JOHN P. CANGIALOSI National Hurricane Center, Miami, Florida (Manuscript received 29 June 2011, in final form 6 November 2011) ABSTRACT The 2010 eastern North Pacific hurricane season was one of the least active seasons on record. Only seven named storms developed, which is the lowest number observed at least since routine satellite coverage of that basin began in 1966. Furthermore, only three of those storms reached hurricane status, which is also the lowest number of hurricanes ever observed in the satellite-era season. However, two tropical storms made landfall: Agatha in Guatemala and Georgette in Mexico, with Agatha directly causing 190 deaths and moderate to severe property damage as a result of rain-induced floods and mud slides. On average, the National Hurricane Center track forecasts in the eastern North Pacific for 2010 were quite skillful. 1. Introduction the maximum sustained wind speed at 6-h intervals for all (sub)tropical storms and hurricanes.

An idealized framework is developed to assess how ventilation affects TC intensity via two pathways: downdrafts outside the eyewall and eddy fluxes directly into the eyewall. Three key aspects are found: ventilation has a detrimental effect on TC intensity by decreasing the maximum steady state intensity, imposing a minimum intensity below which a TC will unconditionally decay, and providing an upper ventilation bound beyond which no steady TC can exist.

The mighty mountain makes up more than fifty percent of the island and is the largest volcano on Earth. Since 1843, when people started rigorously recording Mauna Loa's eruptive activity, the volcano has produced raging lava flows, billowing sulfuric- rich clouds, and giant ground cracks, as well as triggered earthquakes, landslides, and even tsunamis. While geologists and emergency managers are concerned about and actively preparing for a future eruption, Hawaii's general public is largely ignorant or apathetic to their risk.

Received: 27 February 2020; Accepted: 14 April 2020; Published: 17 April 2020 Abstract: The 2014 Northeast Pacific hurricane season was highly active, with above-average intensity and frequency events, and a rare landfalling Hawaiian hurricane. We show that the anomalous northern extent of sea surface temperatures and anomalous vertical extent of upper ocean heat content above 26 ◦C throughout the Northeast and Central Pacific Ocean may have influenced three long-lived tropical cyclones in July and August. Using a variety of satellite-observed and -derived products, we assess genesis conditions, along-track intensity, and basin-wide anomalous upper ocean heat content during Hurricanes Genevieve, Iselle, and Julio. The anomalously northern surface position of the 26 ◦C isotherm beyond 30◦ N to the north and east of the Hawaiian Islands in 2014 created very high sea surface temperatures throughout much of the Central Pacific. Analysis of basin-wide mean conditions confirm higher-than-average storm activity during strong positive oceanic thermal 2 anomalies.

  • NASA Sees a Weaker Hurricane Darby in Infrared Light 19 July 2016
    NASA sees a weaker Hurricane Darby in infrared light 19 July 2016 (NHC). However, NHC noted that Darby still has a well-defined and tight circulation. NHC Forecaster Cangialosi said "Microwave [satellite] data indicates that the low-level center of Darby is located to the south of the eye feature seen in infrared satellite images, which is likely the result of southerly [vertical wind] shear." At 5 a.m. PDT (0900 UTC) on July 19 the center of Hurricane Darby was located near 19.4 degrees north latitude and 134.4 degrees west longitude. That's about 1,345 miles (2,165 km) east of Hilo, Hawaii. The estimated minimum central pressure is 988 millibars. Darby is moving toward the west-northwest near 13 On July 18, AIRS data from NASA's Aqua satellite mph (20 kph) and this motion is expected to showed that strong convection had been decreasing as continue today.
