“…The observed sharp decreasing trend of Thn is not specific to India. Similar decreasing trends in the frequency of Thn activity have been observed worldwide during the second half of the 20th century over parts of the United States (Changnon and Changnon, 2001), parts of Russia and Kazakhstan (Gorbatenko and Dulzon, 2001), tropical Africa (Price and Asfur, 2006), parts of China (Wei et al, 2011;Yu et al, 2016), the Baltic countries (Enno et al, 2014), Yola in northeast Nigeria (Budnuka, 2015), and Pakistan (Mir et al, 2006). Further, Yu et al (2016) found that a decreasing trend in the frequency of thunderstorms over China is due to a decrease in moisture transported over the region resulting from decreasing monsoonal rainfall.…”

RESUMENLas tormentas eléctricas son uno de los fenómenos meteorológicos severos de mesoescala más devastadores, y desempeñan un papel relevante en la incidencia de precipitación en una región. Por ello, en el presente estudio se trató de identificar la relación entre días de tormenta (Thn), días de lluvia (Thr) y cantidad de la precipitación (Trr) en 294 estaciones meteorológicas distribuidas a lo largo de la India por medio de datos (normales climatológicas) publicados por el Departamento Meteorológico de la India (IMD, por sus siglas en inglés) para cuatro periodos: 1951-1980, 1961-1990, 1971-2000 y 1981-2010. El análisis mostró la existencia de una reducción drástica en la frecuencia de Thn, mientras que Thr y Trr mostraron un descenso leve. Se observó una correlación significativa entre las tres variables. El análisis mensual mostró un pico doble en la ocurrencia de Thn y un pico sencillo en la precipitación; sin embargo, se advirtió un intervalo de un mes entre la presentación de estos picos. Estos resultados demuestran que el monzón de verano de la India afecta de manera significativa la actividad de las tormentas eléctricas. El análisis estacional sugiere que Thn, Thr y Trr alcanzaron sus máximos durante la estación del monzón y sus mínimos durante el invierno. Por otra parte, se ha demostrado la existencia de una relación negativa entre Thn y Thr, y Thn y Trr durante el monzón, anomalía que puede deberse a la temperatura decreciente en la India durante dicha estación. Adicionalmente, el patrón espacial mensual y estacional de la ocurrencia de Thn, Thr y Trr permanece casi inalterado en el periodo . No obstante, se observó una disminución drástica en la frecuencia de Thn en los periodos subsiguientes en todo el país. De manera similar, se percibió una leve disminución en la frecuencia de Thr y Trr sobre la India, excepto en el noreste, que exhibe una tendencia al alza en la precipitación. Se ha encontrado que el índice Thn/Thr (R) alcanza su máximo en la temporada previa al monzón, mientras que el índice Trr/Thn alcanza su máximo durante la temporada del monzón. El análisis regional de Thn, Thr y Trr muestra una amplia gama de variaciones en la ocurrencia de estos patrones a lo largo del año. Se considera que los resultados de este estudio serán de utilidad para los meteorólogos, pilotos aviadores, agricultores y planificadores. ABSTRACTThunderstorms are one of the most devastating mesoscale severe weather phenomena, which play an important role in the occurrence of rainfall activity over a region. Therefore, in the present study an attempt has been made to identify the relationship between thunderstorm days (Thn), rainy days (Thr) and rainfall amounts (Trr) for 294 meteorological stations spreading over India, by means of published data (climatological normals) from the India Meteorological Department (IMD) for four periods, 1951-1980, 1961-1990, 1971-2000, and 1981-2010. The analysis has revealed a sharp decrease in the frequency of Thn, while Thr and Trr showed a slight decline. A significant correlat...

“…This decreasing trend in thunderstorms is not peculiar to India. Worldwide, similar downward trends in the frequency of thunderstorms during the second half of the twentieth century have been reported for parts of the USA (Changnon and Changnon, ), parts of Russia and Kazakhstan (Gorbatenko and Dulzon, ), tropical Africa (Price and Asfur, ), Pakistan (Mir et al, ), China (Yu et al, ), the Baltic countries (Enno et al, ) and parts of Nigeria (Budnuka, ). The decreasing trend in the frequency of thunderstorm days over India could be a result of a reduction in atmospheric moisture, which itself is the result of a reduction in the frequency of monsoon depressions (Dash et al, ).…”

How Does the Trend in Thunder Days Relate to the Variation of Lightning Flash Density?

A longstanding question for scientists has been whether or not any observable trends or shifts in global lightning activity have occurred since the Industrial Revolution. This study utilized over 8,000 certified ground‐based stations over a 43‐year period, as well as 16 years of Tropical Rainfall Measuring Mission (TRMM) Lightning Imaging Sensor (LIS) data, to provide a better understanding of the processes behind these trends. Ground station results show that many global regions have observed significant increases or decreases in thunder day occurrence. The Amazon, Maritime Continent, India, Congo, Central America, and Argentina display increases in annual thunder days since the 1970s, whereas China, Australia, and the Sahel among others observe decreases in the number of thunder days. The corresponding change in lightning flash density from the TRMM‐LIS, as well as the number of thunderstorm features and lightning flashes per thunderstorm feature, is compared to the thunder day trends during the TRMM lifespan. Results show a positive correlation between the changes of thunder day occurrence and flash density over most regions of the TRMM domain, including the Maritime Continent, China, South Africa, and Argentina. However, there are several regions with disagreements between the flash density and thunder day trends, such as India and Western Africa. The disagreements are related to the changes in the number of flashes per thunderstorm, which suggest other reasons to interpret the long term trends in thunder day occurrence over various regions. Understanding these regional trends in lightning activity is important in understanding the changes of precipitation systems under a varying climate.
