1987 and 2015

What are the towns in the UK large data set South - North

Cambourne - coastal - windier

Hurn

Heathrow

Leeming

Leuchars (coastal - windier)

As temperature increases sunshine

increases

As temperature increases rainfall

decreases

As temperature increases wind speed

decreases

as we move further north temperature

decreases

as we move further north rainfall

increases

as we move further north max hours of sunshine

increases

because further away from equator means longer summer days

What are the units are temperature and what is it rounded to and typical range

DegreesC

Rounded to 1dp

range approx 5-24

What is daily total rainfall measured in, what is the range

mm

approx 0 - 20mm

what is the daily total sunshine measure in and what is the range

hours

approx 0 - 14hrs

What is the unit and range for cloud cover

oktas

0-8

What is the unit for humidity and that is the range?

%

approx 70 - 100%

What is the unit and range for daily mean viability?

Dm - decametre 1Dm = 10m

approx 200 - 4000 Dm

What is the units and range for pressure?

hPa - hectopascals

approx 990 - 1040 hPa

What is tr?

trace - there was trace of water in the measuring instrument

used for values of rainfall 0 < r ≤ 0.05

replace tr with either 0 or 0.025mm (midpoint)

What do you do if there is data that says n/a

ignore it

What is daily mean windspeed measured in and what is the range

Kn (knots)

approx 3 - 10Kn

What is the windspeed Beaufot conversion?

What is the range

When windspeed is goes from numerical data to qualitative data

light → moderate → fresh → strong

usually light →moderate

What is the units and range for daily max gust

Kn (knots)

approx 8 - 50

What is the difference between daily max gust and daily mean windspeed?

Daily mean windspeed is average whereas daily max gust is the strongest gust of wind

What is the wind/gust direction (bearings/cardinal)

which direction wind is blowing FROM NOT TO - starts from 360degrees

cardinal bearings are basically north, south west etc
