HRD seminar – Stephanie Stevenson, University of Albany SUNY – 28 January 2016

Ms. Stevenson presented a seminar on the “Lightning Observations in Atlantic and East Pacific TCs”.

Abstract:

Global lightning detection has become more reliable in the past decade, allowing for comprehensive observational studies on lightning activity in TCs over the open oceans. This seminar will highlight interesting results from analyses of TCs in the Atlantic and East Pacific from 2005–2014 using the World Wide Lightning Location Network (WWLLN).

The main focus will be on recent results pertaining to inner core (0–100 km) lightning “bursts” and subsequent intensity changes. A case study of Hurricane Earl (2010) found that the occurrence of an inner core lightning burst does not necessarily lead to TC weakening, as some recent studies have suggested. Thus, the relationship between inner core lightning bursts and future intensity change patterns were analyzed in a large ten-year sample of TCs. The dependence of future intensity change was investigated for three factors: the radial burst location, the azimuthal burst location, and the prior intensity change.

Additionally, two other topics will be discussed. First, a diurnal cycle of lightning was observed in some, but not all, major hurricanes, with a radially outward propagation speed similar to the diurnal cycle observed in satellite imagery by Dunion et al. (2014). Second, the azimuthal distribution of lightning varied significantly from the expected shear-dominant relationship when the deep-layer vertical wind shear vector opposed the storm motion vector in East Pacific TCs.

HRD seminar – Dr. Steve Goodman, NOAA/NESDIS GOES-R Program Office – 28 January 2016

Dr. Goodman presented a seminar on the “The GOES-R Geostationary Satellite System and User Readiness”.

ABSTRACT:

NOAA’s Geostationary Operational Environmental Satellites (GOES) have been a mainstay of weather forecasts and environmental monitoring in the United States for the past 40 years. The next generation of GOES satellites, known as the GOES-R Series, is scheduled for launch in October 2016 and will usher in a new era in geostationary environmental satellites. The GOES-R satellites will provide continuous imagery and atmospheric measurements of Earth’s Western Hemisphere that will foster a host of improved and new environmental products and services.

GOES-R’s primary instrument, the Advanced Baseline Imager (ABI), will provide three times the spectral resolution and four times the spatial resolution while scanning the Earth nearly five times faster than the current GOES. GOES-R will also host a new instrument, the Geostationary Lightning Mapper (GLM) that is designed to continuously map in-cloud and cloud-to-ground lightning with 8 km spatial resolution and 80 percent detection efficiency over the Western Hemisphere. It will provide information to improve storm monitoring and warnings and contribute to improved aircraft safety and efficient flight route planning. GOES-R’s space weather instruments will provide improved observations of the sun and space environment with more timely dissemination and early warning to a diverse user community.

This presentation will provide an overview and status update of the GOES-R program and the activities leading to an operational GOES-R system. The new observations will  provide dramatically improved weather, water, and space environmental services in the coming decades, enhancing public safety and providing economic benefits to the U.S. and our international partners.

Paper about improved forecasts of Super Cyclone Sapphire Phailin in the Bay of Bengal published in Earth Interactions

This paper is about weather research conducted by the National Oceanic and Atmospheric Administration and the India Meteorological Department and universities in India and the USA. Very severe cyclonic storm ‘Phailin’ in 2013 was the strongest cyclone to hit the eastern coast of India-Odisha state since the super cyclone of 1999. But there were far fewer deaths in Phailin compared to 1999, when approximately 10,000 people died. During Phailin, a record 1 million people were evacuated from 18,000 villages in both the Odisha and Andhra Pradesh states to coastal shelters due to better forecasts from the Hurricane Weather Research and Forecast and other models.

Important Conclusions:

Research produced better model forecasts of the movement, intensity, rainfall, and storm surge in Phailin.


Timely warnings issued due to these better forecasts minimized property damage and deaths in the affected regions.
