Why Does It Rain In One Locality But Not In Another? Local Rainfall Explained

Heavy rain can fall over one part of Malta while another locality just a few kilometres away remains completely dry.

The same applies to showers and thunderstorms that often develop over the surrounding Mediterranean Sea before reaching land, or missing it altogether.

Local weather page Maltese Islands Weather explained that several factors determine where rain falls.

Winds at different levels of the atmosphere influence where clouds form and the direction and speed at which they move. Moisture is also essential, with water vapour throughout the atmosphere helping to fuel cloud formation and rainfall.

Another key ingredient is atmospheric instability. When warm air rises easily through the atmosphere, it can produce towering clouds, heavy showers and even thunderstorms.

Areas where winds from different directions meet, known as convergence zones, are particularly important because they force air upwards. Even a slight shift in these zones can result in one locality experiencing heavy rain while another nearby receives little or none.

At this time of year, the warm Mediterranean Sea also plays a major role by supplying heat and moisture to the atmosphere. When colder air moves overhead, conditions become favourable for showers to develop.

Because Malta is relatively small, many rain cells are only a few kilometres across. This means a minor change in a storm's path can be enough to bring heavy rainfall to one area while neighbouring localities stay completely dry.
