Winter: December 1st – February 28th/29th (depending on leap-year) In India, the seasons are similar to the meteorological seasons, but monsoon considerations have been inputted. Interestingly, Aboriginal nations around the country have many different seasonal interpretations, ranging from 2-6 distinct seasons. The Aboriginal people of D’harawal, the nation that encompasses part of the Sydney basin and slightly south, define their own six seasons based on the seasonal adapting of flora and fauna. Summer: December 1st – February 28th/29th (depending on leap-year) In Australia, for example, June, July, and August are the coldest months of the year. These are known as the “meteorological seasons” and are based on the annual temperature cycle. Here in Australia as well as New Zealand, Pakistan and Russia, people tend to group whole months together and call them seasons, as defined by our 12-month calendar. Turns out, nobody really agrees on when the seasons start and end. ![]() And you’ve probably felt it too, if you happen to be in the southern or eastern part of the country, like when we saw a QLD town dropping below freezing, cold fronts crossing the country, or thundersnow gracing the alps. You’ve probably heard that winter is finally here, or less likely, it’s ‘just around the corner’. , 5:20PM UTC The winter conundrum: June 1st, June 21st, or other? Unfortunately for them it’s going to turn wintery as the cold front barrels through overnight into tomorrow, increasing cloud cover and showers, with maximum temperatures forecast to reach only 11 and 12☌ from Monday to at least Friday. But for those who live in Melbourne it’s a real treat. So, 7 and 8 hours of sunshine for three days in Melbourne isn’t newsworthy to sunny Sydney. Source: Bureau of Meteorology.īesides two days, Sydney has had over 9 hours of sunshine each day since Friday the 9th. The following map shows the June average sunshine hours across Australia. During June, Melbourne averages about 3.5 hours of sunshine each day compared to Sydney’s average of close to 6 hours. So, what makes people think that? That would be because of the cloudier conditions with more days of light rain and drizzle during the cooler months. ![]() Melbourne is often thought of as a rainier place than Sydney, even though it receives only half the average annual rainfall of Sydney each year. Image: Himawari-9 visible satellite imagery and BoM radar at 12pm Sun 18th This is very fortunate given southeast Australia is currently between two cold fronts. Today marks a third sunny day with a forecast of 8 hours of sunshine but a cooler top of 15☌. On Friday, people were pleasantly surprised with a glorious 8.8 hours of sunshine with a top of 16.5☌. Yesterday, despite the howling wind, Melbourne basked in 7.4 hours of sunshine with a top of 17.6☌. ![]() Melbourne has just experienced some wonderful sunny June days. BMPs were sized to exactly meet the water quality volume for a 2 acre site with 1 acre of impervious, 1 acre of forested land, and annual rainfall of 31.9 inches.Today, 1:28PM UTC Melbourne enjoys some sunny June days See footnote 1 for how these were determined.ġValues were determined using the MIDS calculator. Paul International Airport for different soil types.Īnnual volume, expressed as a percent of annual runoff, treated by a BMP as a function of soil and Water Quality Volume. The table below summarizes annual volume captured by a BMP at the Minneapolis-St. For a B soil, the annual volume captured by the BMP will be about 90 percent. Thus, the annual volume captured by the BMP is much greater than 60 percent. However, for storms exceeding 1 inch in depth, the first inch will be captured by the BMP. Storms up to 1 inch represent about 60 percent of the total volume. A 1 inch storm captures about 90 percent of all rainfall events at Minneapolis-St. For example, consider a BMP designed to capture the first inch of precipitation. In viewing these graphs, note that the volume represents the percent volume captured for a particular size storm and not the cumulative volume. Frequency-volume graphs were developed for several locations in the state and are illustrated below. The methodology and results of this analysis are described in Issue Paper B. In the development of rainfall frequency and volume data for Minnesota, the Minnesota Stormwater Manual Sub-Committee conducted an analysis of rainfall distribution for several locations in Minnesota.
