• Understanding convergence zones and the Intertropical Convergence Zone

  continue to converge, wet conditions can persist, sometimes resulting in significant rainfall totals and even flooding. Convergence lines are not limited to a particular season and can occur at any time of year. During the summer months, local sea breezes can help form convergence lines

• UK and Global extreme events – Heatwaves

  . On a regional scale, Europe, North America, Asia and Australasia have very likely (over 90% probability) observed an increase in heat extremes and decrease in cold extremes. Europe, Asia and Australia have also likely (over 66% probability) observed an increase in heatwaves. Due to less data
