                         from March 20, till April 02, 2020, and it was caused by the 
                         social distancing effort to contain the COVID-19 spread in the 
                         cities. In Sao Paulo, the ratio between cloud-to-ground to 
                         intracloud flashes and the average peak current of negative 
                         cloud-to-ground flashes significantly decreased; whereas in Belo 
                         Horizonte, the ratio between positive and negative cloud-toground 
                         flashes significantly increased with respect to the values in 
                         previous years.",
