  • Assessing and Improving Cloud-Height Based Parameterisations of Global Lightning Flash Rate, and Their Impact on Lightning-Produced Nox and Tropospheric Composition

Luhar ([email protected]) Abstract. Although lightning-generated oxides of nitrogen (LNOx) account for only approximately 10% of the global NOx source, it has a disproportionately large impact on tropospheric photochemistry due to the conducive conditions in the tropical upper troposphere where lightning is mostly discharged. In most global composition models, lightning flash rates used to calculate LNOx are expressed in terms of convective cloud-top height via the Price and Rind (1992) (PR92) 15 parameterisations for land and ocean. We conduct a critical assessment of flash-rate parameterisations that are based on cloud-top height and validate them within the ACCESS-UKCA global chemistry-climate model using the LIS/OTD satellite data. While the PR92 parameterisation for land yields satisfactory predictions, the oceanic parameterisation underestimates the observed flash-rate density severely, yielding a global average of 0.33 flashes s-1 compared to the observed 9.16 -1 flashes s over the ocean and leading to LNOx being underestimated proportionally. We formulate new/alternative flash-rate 20 parameterisations following Boccippio’s (2002) scaling relationships between thunderstorm electrical generator power and storm geometry coupled with available data.

  • Spatial Trends in United States Tornado Frequency
    www.nature.com/npjclimatsci ARTICLE OPEN Spatial trends in United States tornado frequency Vittorio A. Gensini 1 and Harold E. Brooks2 Severe thunderstorms accompanied by tornadoes, hail, and damaging winds cause an average of 5.4 billion dollars of damage each year across the United States, and 10 billion-dollar events are no longer uncommon. This overall economic and casualty risk—with over 600 severe thunderstorm related deaths in 2011—has prompted public and scientific inquiries about the impact of climate change on tornadoes. We show that national annual frequencies of tornado reports have remained relatively constant, but significant spatially-varying temporal trends in tornado frequency have occurred since 1979. Negative tendencies of tornado occurrence have been noted in portions of the central and southern Great Plains, while robust positive trends have been documented in portions of the Midwest and Southeast United States. In addition, the significant tornado parameter is used as an environmental covariate to increase confidence in the tornado report results. npj Climate and Atmospheric Science (2018) 1:38 ; doi:10.1038/s41612-018-0048-2 INTRODUCTION A derived covariate, such as STP, is complementary to tornado Recent trends in global and United States temperature have reports for climatological studies.

  • Evaluation of Rainfall Measurements from the WXT510 Sensor for Use in the Oklahoma City Micronet Jeffrey B
    The Open Atmospheric Science Journal, 2009, 3, 39-47 39 Open Access Evaluation of Rainfall Measurements from the WXT510 Sensor for Use in the Oklahoma City Micronet Jeffrey B. Basara*, Bradley G. Illston, Thomas E. Winning Jr. and Christopher A. Fiebrich Oklahoma Climatological Survey, University of Oklahoma, USA Abstract: A network of 40 real-time, automated atmospheric monitoring stations was deployed in Oklahoma City and of- ficially commissioned on 8 November 2008: the Oklahoma City Micronet (OKCNET). The Oklahoma City Micronet in- cludes 36 stations mounted on traffic signals which utilize the Vaisala WXT510 sensor. As part of the design of the WXT510, an impact sensor is utilized for the collection of rainfall observations. Prior to deployment in Oklahoma City, an array of 33 WXT510 sensors were deployed at the OKCNET intercomparison facility and compared with traditional instruments used to measure rainfall including tipping bucket rain gauges and a Geonor weighing gauge. The results of the comparison revealed that a consistent, linear bias was present between the WXT510 sensors and the traditional gauges whereby, on average, the traditional gauges measured approximately 26% less precipitation than the WXT510 sensors. In addition, the variation in recorded rainfall between WXT510 sensors was consistent with that recorded by the tipping bucket gauges. As such, a correction was developed using the WXT510 and tipping bucket data. This correction was ap- plied to the WXT510 rainfall observations and cross-verified using the Geonor gauge data. The overall result of the study yielded a bulk correction that can be applied to rainfall observations recorded by the WXT510 to greatly improve the ac- cumulated rainfall values.
