| "question": "Given the reported weather events of severe thunderstorms that led to significant rainfall and subsequent flooding, what is the most likely meteorological phenomenon that contributed to the observed temperature spike in time series B on April 26, 2015, and why might this affect future temperature patterns beyond typical seasonal variations?\n\nA) The phenomena were a result of enhanced solar radiation due to the clearing of clouds that accompanied the end of the thunderstorms, leading to significant temperature increases. \nB) The temperature increases were likely the result of a cold front moving through, which typically cools temperatures rather than heating them. \nC) The substantial rainfall and resultant evaporation from the flooding may have initially cooled the atmosphere but could have led to a rapid increase in temperature due to increased humidity and subsequent solar heating as the storms dissipated. \nD) The thunderstorms are likely to have created persistent cloud cover which would have kept temperatures low rather than increasing them.", | |
