General climate analysis

Wind turbine construction

We can provide a wide range of climate analysis data

Our general climate analysis data includes:

Degree day reports

Our degree-day reports provide monthly heating degree-day data (at a standard base temperature of above 15.5 oC for cooling or below 15.5 oC for heating). This report also contains a monthly long term average for comparison and covers approximately 18 regions for a good overview across the UK.

Gust maps

We can provide wind gust maps measuring wind speeds in knots from the network of stations across the UK.

Extreme Value Analysis (EVA)

EVA is a statistical method to estimate the probability and severity of events that are more extreme than any that exists in a given data series. The analysis is typically carried out to assess the potential impact of wind gust on a site/location but we can provide analysis on other elements, such as rain and temperature (minimum and maximum) if required.

Gridded data

We hold a variety of gridded data for a variety of parameters dating back as far as 1960.

Mean Annual Frost Index

This gives a measure of the severity of a period of cold weather and provides a means of assessing likely penetration of frost into a road. Frost index is measured in 'degree days celsius below zero'. We can provide this index for a site of your choice.

Rainfall analysis

UK rainfall analysis reports give the frequency of occurrences of rainfall with an overview of any general trends over the specified time period.

We offer the HM33 (flood studies report) and ITED report. These contain rainfall depth/duration and return period tables - specific to the postcode of your site(s).

These reports are based on the methodology of the Flood Estimation Handbook - the recognised UK methodology for design purposes. The reports show the rainfall amount or intensity versus the duration and frequency.

Storm analysis report

These are tailored reports, created for severe weather events using a range of weather parameters and timescales. The reports supports correlations between weather events and their effects on claims and operations.

We can provide two types of Storm Analysis report:

Legal storm analysis

This has been specifically designed to assist with legal enquiries. It offers standard rainfall statistics and return periods for analysis or comparison.

Standard storm analysis

This provides the same as the above, but includes conclusive summaries and expert weather and climate science opinion.

(Note that this report cannot be used for any legal enquiries).

Wind frequency analysis

This analysis is perfect for wind farm developers to evaluate sites to optimise the use of wind.

It displays the number of simultaneous occurrences of specified ranges of mean hourly wind speed and direction. A wind frequency analysis will also show the percentage frequency of simultaneous occurrences of specified ranges of mean hourly wind speed and direction.

An annual table product provides you with annual figures of the wind frequency as percentages across the different speeds and directions to give an indication of what direction and speed the prevailing wind is from for a particular site.

The full report provides a monthly breakdown of the wind patterns for the particular site alongside the analysis tables providing percentage figures and actual figures for the frequency of wind at a certain direction and speed.

Wind rose reports

A wind rose uses weather data to plot the wind observations by wind direction (plotted as the direction from which the wind is blowing from) and by wind speed (< 1 m/s, 1-3 m/s, 3-5 m/s and >5 m/s) to generate a graphical illustration of the annual, seasonal or monthly wind patterns for a particular station or location.

This product is popular with wind farm developers looking to evaluate sites and potential site designs to optimise the use of wind. It can also help with HSE and environmental compliance regulations.

A graphical annual or monthly representation of the direction and speed of the wind from compass point directions, typically over a 10-year period.

The wind rose shows how often problems with crosswinds are likely to occur, on average. Gust maps and maximum gust analysis are also available.
