A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Rosebery varies significantly throughout the year.

The wetter season lasts 6.1 months, from April 27 to October 30, with a greater than 44% chance of a given day being a wet day. The chance of a wet day peaks at 60% on August 8.

The drier season lasts 5.9 months, from October 30 to April 27. The smallest chance of a wet day is 26% on February 15.

Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 60% on August 8.

Rainfall

To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day of the year. Rosebery experiences extreme seasonal variation in monthly rainfall.

Daylight saving time (DST) is observed in Rosebery during 2017, starting in the spring on October 1 and ending in the fall on April 2.

We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

The perceived humidity level in Rosebery, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, remaining a virtually constant 0% throughout.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

The average hourly wind speed in Rosebery experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 3.5 months, from July 29 to November 15, with average wind speeds of more than 4.4 miles per hour. The windiest day of the year is October 3, with an average hourly wind speed of 5.0 miles per hour.

The calmer time of year lasts for 8.5 months, from November 15 to July 29. The calmest day of the year is February 25, with an average hourly wind speed of 3.9 miles per hour.

The predominant average hourly wind direction in Rosebery varies throughout the year.

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents.

This report illustrates the typical weather in Rosebery, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

Temperature and Dew Point

There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Rosebery.

For each station, the records are corrected for the elevation difference between that station and Rosebery according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

The estimated value at Rosebery is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Rosebery and a given station.

The stations contributing to this reconstruction are: Wynyard West (54%, 125 kilometers, southeast) and Launceston Airport (46%, 142 kilometers, east).

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.

All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.

Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.

Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
