A drone was used to obtain thermal profiles to estimate atmospheric turbulence for the purposes of astronomical observation. The first 150m of height were studied in two areas in the southeast of the Iberian Peninsula. The preliminary results have validated the use of drones as a suitable means of transport for obtaining microthermal measurements. We have also assessed the influence of the planetary boundary layer on the quality of the image for astronomical purposes. In future research, we intend to check these measurements with fixed microthermal sensors installed in meteorological towers.

<p>On 16 November 2023, UK and international researchers gathered at the University of Bath for the 11th CTR Wilson Meeting on atmospheric electricity. The CTR Wilson Institute for Atmospheric Electricity honours the Nobel Prize winner who also pioneered the global circuit concept and published extensively on atmospheric electrical topics. It is integrated with the Special Interest Group of the Royal Meteorological Society, to advance understanding of atmospheric electricity. (<i>Atmospheric electricity</i> concerns diverse and varied electrical phenomenon in the atmosphere, including lightning, atmospheric ionisation and the global electric circuit.) There were 39 registrants for this meeting, which was organised by Martin Fullekrug, Karen Aplin, Alec Bennett, Keri Nicoll and Giles Harrison.

技术包括开尔文水滴均衡器，它使用水滴喷雾来连续测量 PG。1Blair McGinness（雷丁大学）分享了他对用于测量大气电量的点放电传感器的研究。他指出，尽管点放电传感器的使用历史悠久，但人们对其工作原理并不完全了解。他介绍了用同步电场测量校准点放电电流测量的方法。在他的数据中，电流和电场之间存在相位偏移，他在校准中同时使用了静态和动态成分，从而校准了相位偏移。虽然从点放电传感器电流中检索电场并非易事，但传感器对于监测变化仍然有用。接下来，Caleb Miller（雷丁大学）介绍了他在雾中 PG 行为方面的工作，特别是作为雾预测方法的工作。他指出，以前的工作普遍没有定论，可以通过使用更大的多年数据集（如雷丁大学大气观测站的测量数据）来解决。他指出，在许多情况下，这种增加发生得很早，足以为大雾预测提供有用的信息，而不仅仅是能见度测量所能提供的信息。最后一场会议（由 Keri Nicoll 主持）由 David Reid（布里斯托尔大学）致开幕词，他谈到了火星尘埃鬼可能产生的电场和磁场的建模问题。通过简化（例如假设尘埃粒子做圆周运动），他能够利用半径分布、高度分布、电荷分布、旋转频率和粒子负载进行模拟。他的结果与在美国亚利桑那州进行的（极其罕见的）实际尘埃魔测量结果大致相符。本次会议包括贾斯汀-塔比特（布里斯托尔大学）关于气球载放射性探测器的演讲。他介绍说，这种基于 CsI（Tl）闪烁体的粒子探测器是一种可部署在气象气球上的小型仪器，可用于测量对大气电研究非常重要的电离粒子。他介绍了在不同环境下的测试结果，包括客机飞行和热环境试验室。最后一个在线发言是来自 Holle Meteorology & Photography 和马里兰大学的 Ronald Holle 和 Daile Zhang，他们分别介绍了最近出版的一本名为《闪光》（Flash of Brilliance）的书：亚利桑那闪电的科学与奇妙》一书。他们介绍了这本书的各个章节，其中包括有关闪电科学的信息、亚利桑那州闪电研究的历史（包括对 Philip Krider、Kenneth Cummins 和 Richard Orville 的采访）以及亚利桑那州闪电的精美照片。描述单个州或国家闪电研究进展的书籍并不多见。Gayane Karapetyan（马格德堡大学）介绍了闪电气候学，Hripsime Mkrtchyan（雷丁大学）介绍了晴朗天气 PG 分类方法，Keri Nicoll（雷丁大学）介绍了飞机电荷发射器系统，Gregory Marsden（布里斯托尔大学）介绍了火山灰充电。

The summer of 2022 was particularly notable for the prolonged and extensive hot and dry conditions experienced across the UK. The resultant 2022 drought had widespread impacts and prompted much discussion about the continuing vulnerability of the UK to drought, particularly in the context of anthropogenic warming. Here, we briefly describe the evolution of the drought before focusing on the severity of rainfall, river flow, soil moisture and groundwater level deficits from summer 2022, placing the event into a historical context and addressing the impacts of the drought. We also consider whether the 2022 drought is part of a long-term trend towards increasing drought severity.
