Why does it very rarely rain early in the morning.?

Question

I often have to go to work very early in the morning and have noticed that it rarely rains at about 5 a.m. but will rain, if it is going to, later in day.

Also why does it very rarely rain continuously for more than one day?

(These details are for the Midlands in the U.K.)

Answer 1

As temperature rises during the day there will be increased water in the atmosphere from evaporation. Rain can then be caused by the air cooling later in the day or other factors. Also polution builds up during daylight which seeds the clouds. It is also possible that the impact of any high pressure zone from Europe on depressions moving in from the Atlantic is greater during the day.

At 5 a.m. polution and humidity are possibly at their lowest for the daily cycle. Moisture having dropped out as dew overnight along with many particulates.

My personal experience of the West Midlands has been that if you want to take a landscape photograph, then get up early. After noon it will be overcast, or hazy at best.

For it to rain continously for a day anywhere in the world takes special circumstances. It happens in summer when a large ocean storm full of water meets a powerful continental high pressure zone and there is an impasse. This never happens in the Midlands.

Answer 2

Try the Willamette Valley in Oregon. It's always raining in the morning. I have web feet to prove it - Gee Wally

Answer 3

its all down to atmospheric pressure.
just like boiling a kettle of water or a pan of water
in your house the steam builds up it causes droplets
on
your ceiling but if you open a window its not as bad
hence atmospheric pressure....keep dry
happy new year...x..:-)

Answer 4

it does in texas

Answer 5

I am not sure that I agree with either of those statements about the rain! Certainly in all the the places that I have ever lived in (including the Midlands, the North , the South. London and the South West) It seems to me that it rains equally for all hours of the day and night and for both long and short periods. I doubt that Mother Nature selects different conditions for different towns. Although the rainfall pattern is slightly different where there is a terrain with hills and valleys and mountains.

Answer 6

it prolly does but we just don't see it....roll on spring

Answer 7

Meteorologically, there is no observable pattern to support your statement. There is an old saying though

Rain before seven
Fine after eleven.

Again, no proof of that

Answer 8

where do u live?!

Answer 9

Just a guess but possibly as the earth (or where we live on it) starts to warm in the morning sun the evaporation process starts and the moisture rises... Later in the day temperatures and air pressures will equalise... giving better conditions for rain..
