This SBIR Phase II research project will provide research-aircraft and weather-balloon flight tests a new, novel device for measuring the electric field strength of thunderstorms and hurricanes. Electric field strength is a significant factor in the development of precipitation and lightning, and may even play a role in influencing the intensity of precipitation from thunderstorms. Research aircraft flights that typically measure electric field strength in thunderstorms and hurricanes are difficult and potentially dangerous because of the hazardous conditions, such as lightning, hail and turbulence. However, the new device, called an electric field module, can be contained in a device called a dropsonde and dropped through thunderstorms from aircraft flying above the storm, or attached to weather balloons called radiosondes that are released from the ground.Since over 7,000 dropsondes and 400,000 weather balloons are routinely deployed each year, adding electric field measures to these devices represents a substantial commercial market. Measurements using the new E-field modules deployed by the SPEC Learjet research aircraft will be unique and open a new realm for analyzing the structure of electric fields in storms. A more realizable goal is improved aviation safety, by virtue of a better understanding of lightning discharges from clouds associated with thunderstorms, particularly anvil clouds, where commercial aircraft are often struck by lightning.

SBIR第二阶段研究项目将为研究飞机和气象气球飞行测试提供一种用于测量雷暴和飓风电场强度的新型装置。电场强度是降水和闪电发展的一个重要因素，甚至可能影响雷暴降水的强度。通常测量雷暴和飓风中电场强度的研究飞机飞行是困难的，并且由于闪电，冰雹和湍流等危险条件而具有潜在的危险。然而，这种新装置被称为电场模块，可以装在一种名为下投式探空仪的装置中，从飞行在雷暴上空的飞机上投下，或者装在从地面释放的名为无线电探空仪的气象气球上。由于每年例行部署的下投式探空仪和气象气球超过7,000个，向这些装置增加电场测量代表了一个巨大的商业市场。使用SPEC Learjet研究飞机部署的新电场模块进行的测量将是独一无二的，并为分析风暴中电场结构开辟了一个新的领域。一个更可实现的目标是通过更好地了解与雷暴有关的云层，特别是砧云的闪电放电来改善航空安全，因为商用飞机经常被闪电击中。
