• Met Office explains: How is thunder formed?

  coast, but elsewhere in the UK, summer is typically the most thundery season. This variability means that maps showing thunderstorm frequency can differ depending on the period of record used. What causes lightning? Lightning is the precursor to thunder and forms within storm clouds through

  characteristics of the East Asian Summer Monsoon compared to regional scale models, including the daily cycle of rainfall across many regions of China. Li et al (2019) focussed on an event in 2016 where 600mm of rainfall fell over parts of eastern China in just 6 days leading to catastrophic flooding

  but probabilities of a wetter season than last year and of 10-year extremes are presented. A wetter season than 2018 is favoured in most boxes east of 30E and between 10N and 10S. Elsewhere a drier season than 2018 is likely in most grid boxes. Probabilities of a season drier than any in the past 10 years (2009

• 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

There is a relative insensitivity to domain size for simulating some important features of the regional circulation and key rainfall characteristics e.g. the Caribbean low level
