Golden Bay New Zealand- Takaka

Paynes Ford Station



What do the Weather Display Live dials mean?


Trouble understanding what is actually on the WDL page? This should explain it all.... 

2018 Upgrade.....WDL was using Adobe Flash to run, which is no longer supported by Adobe and has been phased out by many browsers. My son has been taken it onto himself to do a html5 version and it was presented to this site as a Christmas present. How cool is that?! It took him al lot of time and dedication, so I am very grateful and pleased that it is now showing on mobile phones and runs on Macs and all that. In the next few months tweaks and additions are to follow, but for now....hat off to Yerren!

This page will consequently become redundant and need a re-write, but for a while the old WDL version will be up still also and in terms of functionality the old and the new version are not very different, just the looks.

-Blinking thingie at left top corner....Updates from the weather station to this website take place in various steps with a time delay for each step (for example the upload from computer to website alone will take several seconds). Every 10 seconds data will be uploaded from the computer to the website. The time after the blinking thingie is the latest upload time and a short red blink means the upload of current data just happened. Sometimes there is a hiccup along the line -> weather measuring instruments-receiving console-data logger-computer-website <- and there won't be any data feeds for a couple of minutes until the system resets. Or some system crash or computer downtime of some sort may cause the data feed to stop for longer periods.

-Alternating text next and under Paines Ford station name......Date and time of latest data feed/Current conditions and forecast, generated by the weather station for the next 24-48 hours or done manually (indicated by "Updated on ...by René ") updated whenever appropriate. Due to a huge number of variables forecasting always contains a margin of error. Sometimes a narrow band of rain may just pass the Bay or may go over it depending on the wind. Or a front may be blocked by a High, but where does it stop, over the Bay or just before it? For that reason there will be the following confidence ratings for the 24-48 hr range of the forecast: Conf. High, Conf. Medium or Conf. Low (for Confidence High,Medium or Low), mentioned at the end.

-Weather Icon .... Displays the current weather condition at Paynes Ford, sort of ehr....animated web cam?

-Fire weather Index.....The weather station's software calculates the risk of fire in the outdoors.

-Sun/Moon rise/set.... Happens every day! At different times! Even tells the moon phase.

-Temperature.....There is the biggest gauge, pretty straightforward, the temperature (tata!) as measured outside. But then there are the so called perceived temperatures. Wind chill/heat index/humidex/apparent temperature and my favourite THSW (temp-humidity-sun-wind) which really takes all those variables into account when establishing how we perceive the temperature. Of course there is a lot of confusion of how we should calculate these figures and what they really mean. Is the wind chill only valid if we dance in our togs in an antarctic gale? How apparent is the sunshine when I wear many layers under my skiing gear? Anyway, I thought to just include a couple of these and to make things more wacky they will even change depending on temperature or not tell anything different when there is no wind.

Maximum and minimum daily re-set is at midnight.

-Wind dials.....measure speed and direction of the wind. The wind speed is measured by the anemometer every 2-3 seconds and a gust is every one of these measurements, whereas the wind is the average of 10 minutes worth of these measurements. As a guideline wind speeds of 0-10 km/h are generally not intrusive, 11-20 km/h are noticable windy, 21-30 km/h are very annoying (plan to be inside) and above that we start to get into serious storm weather. Please note that the winds may be a fair bit stronger at the beaches in the Bay, also depending on their orientation.

-Cloud Base.... The cloud base is calculated. It's pretty good when there are clouds. But when there are no clouds the cloud base will indicate the height that clouds MAY/COULD form (if air movement allows). I attempted training the kids to report if there are any clouds at two minute intervals, but they lost interest quickly. So that's where the solar gauge comes in handy. 100% solar means no clouds between the station and the sun (there may still be clouds around) and less than 100% solar means some sort of cloud cover. Or some bird sitting on top of the solar instrument.

Evapotranspiration (ET).... Evaporation of rain that has fallen, reverse rain, what comes down must go up etc. As rain it is measured in mm (millimeters).

Graphs.... Various trends for the last 24 hours or the rainfall for the last 31 days (i.e. -1 = yesterday, -2 - the day before yesterday, -7 a week ago and so on). At the bottom there is also a graph button which will give you more graph options, good if you want to get an idea about the weather data for the past month or so. The Records button there will show the extremes for the last month, the current year and all time extremes.

Please note: In November 2012 the temperature/humidity probe has been re-located to a better position in terms of accurate maximum temperature readings. All (all time and year to date) highest temperature settings have been re-set at that time.

Barometer....air pressure, calibrated to the altitude of the Paines Ford weather station, so that the reading corrresponds with the pressure at sea level and the isobars on the weather charts of the meteorological info providers (Metservice/B.O.M. Australia).

Humidity/Hygrometer..... Relative humidity of the outside air or how much water vapour the air contains compared to air that is saturated to the point that drops begin to form (rain/fog). Warmer air can hold more water vapour, so relative humidity lowers when the same air/water vapour mixture is heated and vice versa.

UV....UV radiation can be bad for the skin, but is necessary for natural production of Vitamin D in the body. All good things in moderation and best to pick the times of the day wisely when visiting Willie's swimming hole here at Paines Ford or one of the Bay's many beaches. UV index ratings over 7 will result in skin burn times of less than 15 minutes for fair skinned people.

Solar.....solar energy output in Watts/square meter. The percentage is based on the normal readings at the Paynes Ford lattitude and longitude for that specific time/day of the year, so 100% means the sun is not obstructed by any clouds and lower percentages indicate a thicker cloud cover. Short of a web cam, this has proven to be pretty accurate for getting an idea about the current conditions in Paines Ford. During the warmer months the reading may be down to 85%, without seemingly any clouds around. This normally goes hand in hand with hazy conditions and/or a thin layer of high cloud. New!!-Now also reports the hours of sunshine for the current day.

Rain gauges.....rain for the day, month and year to date. Sometimes it also shows yesterday's rain or the rain rate at any given time, as in the amount of rain falling per minute. Daily re-set is at midnight.
