Nonlocal Inadvertent Weather Modification Associated with Wind Farms in the Central United States
Hindawi Advances in Meteorology Volume 2018, Article ID 2469683, 18 pages https://doi.org/10.1155/2018/2469683 Research Article Nonlocal Inadvertent Weather Modification Associated with Wind Farms in the Central United States Matthew J.

Local effects of inadvertent weather changes within and near wind farms have been well documented by a number of modeling studies and observational campaigns; however, the broader nonlocal atmospheric effects of wind farms are much less clear. )e goal of this study is to determine whether wind farm-induced perturbations are able to evolve over periods of days, and over areas of thousands of square kilometers, to modify specific atmospheric features that have large impacts on society and the environment, specifically midlatitude and tropical cyclones. Here, an ensemble modeling approach is utilized with a wind farm parameterization to quantify the sensitivity of meteorological variables to the presence of wind farms. )e results show that perturbations to nonlocal midlatitude cyclones caused by a wind farm are statistically significant, with magnitudes of roughly 1 hPa for mean sea- level pressure, 4 m/s for surface wind speed, and 15 mm for maximum 30-minute accumulated precipitation. -
Known Impacts of Tropical Cyclones, East Coast, 1858 – 2008 by Mr Jeff Callaghan Retired Senior Severe Weather Forecaster, Bureau of Meteorology, Brisbane
ARCHIVE: Known Impacts of Tropical Cyclones, East Coast, 1858 – 2008 By Mr Jeff Callaghan Retired Senior Severe Weather Forecaster, Bureau of Meteorology, Brisbane The date of the cyclone refers to the day of landfall or the day of the major impact if it is not a cyclone making landfall from the Coral Sea. The first number after the date is the Southern Oscillation Index (SOI) for that month followed by the three month running mean of the SOI centred on that month. This is followed by information on the equatorial eastern Pacific sea surface temperatures where: W means a warm episode i.e. sea surface temperature (SST) was above normal; C means a cool episode and Av means average SST Date Impact January 1858 From the Sydney Morning Herald 26/2/1866: an article featuring a cruise inside the Barrier Reef describes an expedition’s stay at Green Island near Cairns. “The wind throughout our stay was principally from the south-east, but in January we had two or three hard blows from the N to NW with rain; one gale uprooted some of the trees and wrung the heads off others. The sea also rose one night very high, nearly covering the island, leaving but a small spot of about twenty feet square free of water.” Middle to late Feb A tropical cyclone (TC) brought damaging winds and seas to region between Rockhampton and 1863 Hervey Bay. Houses unroofed in several centres with many trees blown down. Ketch driven onto rocks near Rockhampton. Severe erosion along shores of Hervey Bay with 10 metres lost to sea along a 32 km stretch of the coast. -
6. Annual Review and Significant Events
6. Annual Review and Significant Events January-April: wet in the tropics and WA, very hot in central to eastern Australia For northern Australia, the tropical wet season (October 2005 – April 2006) was the fifth wettest on record, with an average of 674 mm falling over the period. The monsoon trough was somewhat late in arriving over the Top End (mid-January as opposed to the average of late December), but once it had become established, widespread heavy rain featured for the next four months, except over the NT and Queensland in February. One particularly noteworthy event occurred towards the end of January when an intense low (central pressure near 990 hPa) on the monsoon trough, drifted slowly westward across the central NT generating large quantities of rain. A two-day deluge of 482 mm fell at Supplejack in the Tanami Desert (NT), resulting in major flooding over the Victoria River catchment. A large part of the central NT had its wettest January on record. Widespread areas of above average rain in WA were mainly due to the passages of several decaying tropical cyclones, and to a lesser extent southward incursions of tropical moisture interacting with mid-latitude systems. Severe tropical cyclone Clare crossed the Pilbara coast on 9t h January and then moved on a southerly track across the western fringes of WA as a rain depression. Significant flooding occurred around Lake Grace where 226 mm of rain fell in a 24-hour period from 12 t h to 13 t h January. Tropical cyclone Emma crossed the Pilbara coast on 28 th February and moved on a southerly track; very heavy rain fell in the headwaters of the Murchison River on 1s t March causing this river’s highest flood on record. -
In the Aftermath of Cyclone Yasi: AIR Damage Survey Observations
AIRCURRENTS By IN THE AFTERMATH OF CYCLONE YaSI: AIR DAMAGE SURVEY OBSERVATIONS EDITOR’S NOTE: In the days following Yasi’s landfall, AIR’s post-disaster survey team visited areas in Queensland affected by the storm. This article 03.2011 presents their findings. By Dr. Kyle Butler and Dr. Vineet Jain Edited by Virginia Foley INTRODUCTION Severe Cyclone Yasi began as a westward-moving depression In addition to the intense winds, Yasi brought 200-300 off Fiji that rapidly developed into a tropical storm before millimeters of precipitation in a 24 hour period and a storm dawn on January 30, 2011. Hours later, Yasi blew across the surge as high as five meters near Mission Beach. northern islands of Vanuatu, continuing to grow in intensity and size and prompting the evacuation of more than 30,000 residents in Queensland, Australia. By February 2 (local time), the storm had achieved Category 5 status on the Australian cyclone scale (a strong Category 4 on the Saffir-Simpson scale). At its greatest extent, the storm spanned 650 kilometers. By the next day, it became clear that Yasi would spare central Queensland, which had been devastated by heavy flooding in December. But there was little else in the way of good news. Yasi made landfall on the northeast coast of Queensland on February 3 between Innisfail and Cardwell with recorded gusts of 185 km/h. Satellite-derived sustained Figure 1. Satellite-derived 10-minute sustained wind speeds in knots just after wind speeds of 200 km/h were estimated near the center Cyclone Yasi made landfall. -
Cyclone Tracey-Key Findings.Pdf
Historical case studies of extreme events Key findings: Cyclone Tracy 22/12-15:30 The event Cyclone Tracy was a Category 4 cyclone 22/12-21:00 that laid waste to the city of Darwin in the Northern Territory early on Christmas morning 1974. 23/12- 01:30 Cyclone Tracy showed the nation just how 23/12- 09:00 devastating the impact of a cyclone could be, and awoke the engineering community, local and international, to the true risk of cyclonic wind storms. Tracy’s small size minimised the spatial 23/12- 21:00 extent of damage, but her slow forward speed meant the areas beneath her storm track were completely devastated. 24/12- 09:00 Cyclone Tracy resulted in 71 deaths and 650 injuries. Fortunately for Darwin, flooding and 24/12- 13:00 storm surge were not major issues or these 24/12- 18:30 numbers could have been far higher. 24/12- 21:00 In almost all cases wind was the dominant 25/12- 00:30 factor in the ensuing structural damage, 25/12- 03:00 which left 94% of housing uninhabitable, Darwin approximately 40,000 people homeless and 25/12- 09:00 necessitated the evacuation of 80% of the 25/12- 12:00 city’s residents.

TRENDS IN TROPICAL CYCLONE IMPACT A Study in Andhra Pradesh, India BY S. RAGHAVAN AND S. RAJESH Increasing damage due to tropical cyclones over Andhra Pradesh, India, is attributable mainly to economic and demographic factors and not to any increase in frequency or intensity of cyclones. t is generally accepted that, all over the world, map, Fig. 1). The damage during the past quarter cen- property damage from tropical cyclones (TC) has tury, in the coastal state of Andhra Pradesh in India Iincreased over the years. There is a common per- (Fig. 2), has been normalized for inflation, population ception in the media, and even in government and management circles, that this is due to an increase in tropical cyclone frequency and per- haps in intensity, probably as a result of global climate change. However, studies all over the world show that though there are decadal variations, there is no defi- nite long-term trend in the frequency or intensity of tropical cyclones. In this paper, we review recent worldwide literature on trends in tropical cyclone frequency, intensity, and impact, with special reference to the North Indian Ocean (NIO) ba- sin, that is, the Bay of Bengal (BoB) FIG.

Polarimetric Radar Observations of the Persistently Asymmetric Structure of Tropical Cyclone Ingrid
616 MONTHLY WEATHER REVIEW VOLUME 136 Polarimetric Radar Observations of the Persistently Asymmetric Structure of Tropical Cyclone Ingrid PETER T. MAY,J.D.KEPERT, AND T. D. KEENAN Bureau of Meteorology Research Centre, Melbourne, Australia (Manuscript received 3 November 2006, in final form 3 May 2007) ABSTRACT Tropical Cyclone Ingrid had a distinctly asymmetric reflectivity structure with an offshore maximum as it passed parallel to and over an extended coastline near a polarimetric weather radar located near Darwin, northern Australia. For the first time in a tropical cyclone, polarimetric weather radar microphysical analyses are used to identify extensive graupel and rain–hail mixtures in the eyewall. The overall micro- physical structure was similar to that seen in some other asymmetric storms that have been sampled by research aircraft. Both environmental shear and the land–sea interface contributed significantly to the asymmetry, but their relative contributions were not determined. The storm also underwent very rapid changes in tangential wind speed as it moved over a narrow region of open ocean between a peninsula and the Tiwi Islands. The time scale for changes of 10 m sϪ1 was of the order of 1 h. There were also two distinct types of rainbands observed—large-scale principal bands with embedded deep convection and small-scale bands located within 50 km of the eyewall with shallow convective cells. 1. Introduction larimetric radar (Keenan et al. 1998).

Developing Impact-Based Thresholds for Coastal Inundation from Tide Gauge Observations
CSIRO PUBLISHING Journal of Southern Hemisphere Earth Systems Science, 2019, 69, 252–272 https://doi.org/10.1071/ES19024 Developing impact-based thresholds for coastal inundation from tide gauge observations Ben S. HagueA,B,C, Bradley F. MurphyA, David A. JonesA and Andy J. TaylorA ABureau of Meteorology, GPO Box 1289, Melbourne, Vic. 3001, Australia. BSchool of Earth, Atmosphere and Environment, Monash University, Clayton, Vic., Australia. CCorresponding author. Email: [email protected] Abstract. This study presents the first assessment of the observed frequency of the impacts of high sea levels at locations along Australia’s northern coastline. We used a new methodology to systematically define impact-based thresholds for coastal tide gauges, utilising reports of coastal inundation from diverse sources. This method permitted a holistic consideration of impact-producing relative sea-level extremes without attributing physical causes. Impact-based thresh- olds may also provide a basis for the development of meaningful coastal flood warnings, forecasts and monitoring in the future. These services will become increasingly important as sea-level rise continues.The frequency of high sea-level events leading to coastal flooding increased at all 21 locations where impact-based thresholds were defined. Although we did not undertake a formal attribution, this increase was consistent with the well-documented rise in global sea levels. Notably, tide gauges from the south coast of Queensland showed that frequent coastal inundation was already occurring. At Brisbane and the Sunshine Coast, impact-based thresholds were being exceeded on average 21.6 and 24.3 h per year respectively. In the case of Brisbane, the number of hours of inundation annually has increased fourfold since 1977. -
