Meteorological autumn is upon us, and usually that means that the mighty polar vortex is about to make its seasonal return. You can read in the article linked below what the polar vortex is and why it forms every year. Polar vortex: What is it, and why you should care? Every autumn when the north hemisphere receives less light and heat from the sun, the polar region start to cool. Due to the processes described in the article linked above, pressure starts to drop as the atmosphere above the North Pole starts to cool. What forms higher in the stratosphere is similar to a large cyclone. Its not the same, but it is easier to explain it as a large […]
Tropical Atlantic getting active. Invest-96L could develop into a major hurricane, impacting the Caribbeans.
We are at the peak of the hurricane season, and we are already looking ahead at the possibility of new storms developing. We already talked today about the Tropical depression 9 forming, but now we also have Invest-96L, which is an area of deep convection, but could soon become a tropical storm. Invest-96L is currently just an area under observation, but it shows strong signs of potential development. There is deep convection already present, and it is currently moving west into more favorable conditions for further development. IR satellite imagery of Invest-96L area. Image by Tropical Tidbits. It is not easy for models to forecast this development, since there is no well defined center of low pressure and circulation. Still, […]

It is currently not projected to become a hurricane, but latest strength forecasts are not yet reliable, since the depression is not fully formed yet. Deep convection can already be seen on the satellite, rising around the center of the developing depression. Current IR satellite imagery of the forming depression. Image from Tropical Tidbits. The official forecast is for the system to become a tropical storm, moving into Florida tomorrow. Current official path outlook from the National Hurricane Center. General multi-model forecast is to bring tropical storm conditions to Florida, with […]

Loodus hakkab vaikselt oma lillesilmi kinni panema ja seetõttu rõõmustame iga lilleõie üle aias ja metsateel.
Minu eriline armastus aialillede seas on lõvilõug, küllap sellepärast, et ta minu sünnipäeva paiku vanasti õitses. Nüüd võib õitsvaid lilli pea aasta läbi lillepoodidest leida.
Lõvilõugadega sai lapsena ikka lõvi mängitud. Vajutasid õie külgedelt “lõvi lõuad lahti” ja siis teine laps pani oma näpu sinna sisse. Lõvilaps lasi lõuad kinni kukkuda ja möirgas hirmsasti.
