    "description": "Satellite loops show tropical storms gathering into vast clumps that live for days. Divya Sri Praturi asks why convection organises itself with no mountains or coastlines to guide it. In this short she explains convective self-aggregation, the feedbacks of moisture and radiation behind it, and why clustered storms dry the tropics, change extreme rainfall, and alter how the planet sheds heat.",

        "summary": "In idealised simulations, randomly scattered storms drift into a single moist cluster surrounded by desert-dry air: self-aggregation. Radiative cooling of dry regions and moisture memory drive the clumping. The degree of clustering controls extreme rain and how easily the tropics radiate heat to space, making organisation a first-order climate question."
