    Summary:© 2016 IEEE. In recent years, there has been a significant increase in the damage to electrical and electronic devices owing to lightning surge-induced overvoltage/overcurrent, in Japan. In particular, the lightning surge overcurrent that flows through grounding lines can cause serious damage to electronic equipment. To understand the phenomenon of the lightning surge current propagation in the ground poles, it is important to understand the lightning current propagation in the soil. We have developed a detection circuit for determining the lightning current distribution in the soil and have measured the lightning current caused by rocket-Triggered lightning in the soil. We have observed the lightning current in the soil owing to a negative precursor discharge at a depth of 0.1 m, 30 m from the triggered flash point.

    Summary:We have been developing EM source location system in VLF/LF bands based on broadband digital interferometry to monitor lightning activities in a wide area. Since EM waves in VLF/LF radiated by lightning discharges propagate a long distance, the VLF/LF interferometer locates lightning discharges a few hundred kilometers away from the VLF/LF interferometer. We conducted lightning observation campaign by a prototype of a VLF/LF band digital interferometer and VHF band digital interferometers in Darwin, Australia. Horizontal distances between VLF/LF and VHF band locations show that VLF/LF radiation sources were located near those of VHF source. We succeeded in locating VLF/LF radiation sources associated with return strokes near the ground.

    Summary:We examine spectra of VHF electromagnetic (EM) waves obtained by a VHF Digital Broadband Interferometer (DITF) operated on the ground. The DITF is a two- and three-dimensional VHF source mapping system for VHF EM waves in band between 25 and 100MHz based on a technique of the broadband digital interferometry. We divide leaders into two classes by an aspect of leader development based on three-dimensional discharge channels. The spectra of VHF EM waves associated with the leaders progressing to the ground peaks around 25MHz, while that of the leaders propagating horizontally inside thunderclouds peaks around 40MHz.

    Summary:Lightning and sprite measurement sensors on the International Space Station (ISS) are introduced in this paper. Lightning is an electrical discharge which neutralizes the charge inside thunderstorm. In the early 1990s, optical transient luminous events (TLEs) occurring just above the thunderstorm were firstly reported by the US scientists and are associated with positive cloud-to-ground discharges with a large amount of charge. Though the luminous events so-called sprite, elves and jets have been investigated by numerous researchers all over the world based mainly on the ground observations, some important problems have not been fully understood yet such as generation mechanisms of columniform fine structure and horizontal offset of some sprites from the parent lightning discharges. In the JEM-GLIMS mission, observations from our synchronized sensors are going to shed light on above-mentioned unsolved problems regarding TLEs as well as causative lighting discharges. Our goals are (1) to detect and locate lightning and sprite within storm scale resolution over a large region of the Earth's surface along the orbital track of the ISS without any bias, (2) to clarify the generation mechanism of sprite, and (3) to identify the occurrence conditions of TLEs.

    Summary:In this report, we describe the outline of the GLIMS equipment equipped with the JEM exposed facility and the development of the equipment as an engineer belonging to the department of mechanical engineering of the university. Especially, we developed the equipment by the cooperation of Department of Science and Department of Engineering in the development of this mission equipment without ordering to the specialty company of the space appliance. We describe how the teacher at the university that is involved in mechanical engineering should be related to development so that Department of Science may cooperate with Department of Engineering.

    Summary:The VHF broadband digital interferometer (DITF) observed two- (2D) and three-dimensional (3D) developments of summer positive cloud-to-ground (CG) lightning flashes with high time resolution. The characteristics of summer positive CG lightning flashes attract a great deal of interest. In the first stage, the in-cloud negative breakdown progresses about 15 km horizontally between 6 and 10 km high. In the next stage, the lightning location and protection system (LLS) detects the positive lightning stroke near the initiation point of the preceding negative breakdown. In the last stage, the negative breakdown runs through the channel of the first negative breakdown. For the positive return stroke to run through the first negative channel, the positive leader, which is not visualized by the DITF, progresses from the initiation point of the first negative channel and touches to the ground. The return stroke current propagates and penetrates in the opposite direction as visualized subsequent negative breakdown. This suggests the negative and positive breakdown progress together. To realize this situation, we conclude the necessity to apply the bi-directional leader progression concept. In a word, we observed bi-directional leaders in summer nature positive CG lightning flashes.

    Summary:A high resolution radar has been newly developed and tested recently in order to observe the fine structure of thunderstorm. Lightning location system which determines the sources of the VHF impulses emitted from lightning also implemented near the radar site. The initial observation shows that a ground flash initiated near 0 degree level just above the thunderstorm core and propagated to the ground along the edges of the thunderstorm, suggesting that the simultaneous observation with lightning and high resolution radar system will be novel tool for lightning research and prediction.

    Summary:In order to study the generation mechanism of lightning-associated transient luminous events (TLEs) and the relationship between lightning and TLEs, we will carry out the lightning and TLE observation at Exposed Facility of Japanese Experiment Module (JEM-EF) of International Space Station (ISS). In this mission named JEM-GLIMS (Global Lightning and sprlte MeasurementS on JEM-EF) two kinds of optical instruments and two sets of radio receivers will be integrated into the Multi mission Consolidated Equipment (MCE) which is the bus system and will be installed at JEM-EF finally. For the development of the GLIMS instruments, mechanical FEM analysis and thermal analysis are the important tasks to be performed by the mission team. Science group of the GLIMS mission has contacted to professors who belong to the department of engineering in an university and are an expert of the mechanical and thermal analysis. By their tremendous cooperation, GLIMS mission could pass the numerous reviews. Though many science mission using very small satellite will be planned in near future, strong mutual cooperation between science group and engineering group is important.

    Summary:Lightning Research Group of Osaka University (LRGOU) has been developing two- (2D) and three-dimensional (3D) VHF source mapping system for electromagnetic (EM) waves emitted associated with lightning discharge progression based on a unique technique of the broadband digital interferometry. The spatial accuracy of the interferometer is influenced by its installation errors. In this paper, we propose a simplified calibration of these installation errors using broadcast waves, and assess spatial accuracy of the interferometer after removal of installation errors.

    Summary:Hazardous weather such as severe storms, tornadoes and hurricanes are small scale weather phenomena. and their detailed profiles are important practically and scientifically. Despite this, conventional radars cannot resolve them, because of their low resolution capability. In this study, we developed a new high resolution Ku-band Doppler radar with scanning capability for meteorological applications. With the new system design, the radar can accurately measure the radar reflectivity factor with the range resolution of 4m and the time resolution of 1min per 1 volume scan (VoS) from the nearest range of 50m to about 15km for 10W power using pulse compression technique. In this paper, details of the system design and signal processing algorithm are described. To demonstrate the accuracy of this system, the radar reflectivity measurements are compared with 2D video disdrometer measurements, and fairly good agreement is shown. In addition, we observed a tornado of F0 scale using this radar and succeeded in detecting the detailed structure.

    Summary:Estimates of precipitation at a high time and space resolution are required for many important applications. In this paper, a new global precipitation map with high spatial (0.1 degree) and temporal (1 hour) resolution using Kalman filter technique is presented and evaluated. Infrared radiometer data, which are available globally nearly everywhere and nearly all the time from geostationary orbit, are used with the several microwave radiometers aboard the LEO satellites. IR data is used as a means to move the precipitation estimates from microwave observation during periods when microwave data are not available at a given location. Moving vector is produced by computing correlations on successive images of IR data. When precipitation is moved, the Kalman filter is applied for improving the moving technique in this research. The new approach showed a better score than the technique without Kalman filter. The correlation coefficient was 0.1 better than without the Kalman filter about 6 hours after the last microwave overpasses, and the RMS error was improved about 0.1 mm/h with the Kalman filter technique. This approach is unique in that 1) the precipitation estimates from the microwave radiometer is mainly used, 2) the IR temperature in every hour is also used for the precipitation estimates based on the Kalman filter theory.
  • VHF Observations from a Small Satellite, MORIMOTO Takeshi, USHIO Tomoo, KAWASAKI Zen, IEICE technical report, 106, 224, 1, 6,   2006 08 25 , http://ci.nii.ac.jp/naid/110004823450
    Summary:Lightning Research Group of Osaka University (LRG-OU) has been developing VHF Broadband Digital Interferometer (DITF) to image precise lightning channels and monitor lightning activity widely. The feature of broadband DITF is its bandwidth (from 25MHz to 100MHz) and implicit redundancy for estimating VHF source location. Since the VHF broadband DITF own the superiority to image lightning channels with rather short base line, LRG-OU considers an application of BDITF to the space-borne measurement system. One of the possibilities to realize the idea is a Panel Extension Satellite (PETSAT). PETSAT may consist of some independent panels. Each panel will be designed to own individual function and the configuration of PETSAT is adjustable depending on the objectives. Since it is shown that the short baseline of DITF could accomplish the high time and space resolution for VHF source locations, we can reach an idea of VHF broadband DITF operation on PETSAT. PETSAT is planed to be a low altitude satellite about several hundred kilometers from the ground, and the locations accuracy of 0.01 radians may provide us the sufficient and unique opportunity to discriminate between the active thundercloud from non active ones by satellite observations. We are expecting to launch PETSAT by 2007.

    Summary:熱帯降雨観測衛星(TRMM;Tropical Rainfall Measuring Mission)に搭載されている降雨レーダー(PR;Precipitation Radar)及び雷観測装置(LIS ; Lightning Imaging Sensor)のデータを用いて,単位時間単位雷雲セル当たりの発雷数であるflash rateのパラメタリゼーションを行う.現在までflash rateと降雨頂高度(storm height)の関係に対する議論はなされてきたが,未だ明確な結論は出ていない.本論文では定義を見直したflashrateと,storm heightだけでなくfreezing levelから降雨頂までの距離に相当するsnow depth との関係について考察する.季節及び地域を分類しないとき,flash rate はstorm height及びsnow depth のそれぞれ7.5乗,5.2乗に比例する.しかし,季節・地域の分類を行うとstorm heightの冪数は大きく変化するのに対しsnow depth のそれは大きく変化しない.よってstorm heightよりもsnow depthでより正確なパラメタリゼーションが可能であり,flash rateはsnow depthの約5乗に比例することが明らかとなった.
