The present climate circumstances in Türkiye resemble these of fifty years in the past as a result of intense rainfall in November, in line with professor Mikdat Kadıoğlu, the pinnacle of the Department of Meteorological Engineering at Istanbul Technical University.
Kadıoğlu defined on Sunday that the system inflicting heavy rainfall, which started in the midst of this month, is a return to Türkiye’s climate patterns from half a century in the past. He attributed this phenomenon to the truth that polar areas have warmed greater than the equator attributable to world warming. Consequently, heat and chilly fronts have been passing by the northern areas of the nation extra steadily lately.
Highlighting the impression of local weather change on precipitation, Kadıoğlu expressed concern that winters aren’t receiving enough snowfall and different precipitation as heat, convective rainfalls, sometimes noticed through the hotter months, have develop into extra prevalent.
“In the days corresponding to November this year, a low-pressure center, along with the associated warm and cold front, made its way from the Balkans to Iran, bringing the much-needed rainfall we have been missing,” Kadıoğlu acknowledged. He emphasised that the motion of this low-pressure heart alongside the northern a part of Istanbul and the Black Sea coast resulted in heavy rainfall and robust winds.
Drawing consideration to the formation of robust winds in areas the place the rotation and motion course of the low-pressure heart are parallel, Kadıoğlu defined that the unfavourable state of the North Atlantic Oscillation (NAO) is another excuse for the present publicity to this mid-latitude storm. NAO refers to adjustments within the values of two strain methods, the Iceland Low Pressure and the Azores (Bermuda) High Pressure, positioned above the North Atlantic Ocean.
Regarding the extreme rainfall from the current entrance system, Kadıoğlu attributed it to the consecutive motion of storm cells alongside the entrance line in a southwest-to-northeast course, just like prepare vehicles.
“In summary, the frontal system we encountered in the middle of November this year represents our weather system from 50 years ago – a memory from a time when climate change did not affect the orbits of low-pressure centers,” Kadıoğlu concluded.
Surface, water
Commenting on the speedy incidence of rainfall in storm strains, Kadıoğlu emphasised the erosive impression of raindrops on naked soil, significantly in rural areas. He defined that in city areas with impermeable surfaces like concrete and asphalt, rainfall rapidly transitions to floor move, resulting in points reminiscent of flooded roads and basements.
Kadıoğlu highlighted the significance of rainwater harvesting for water conservation in Türkiye, a rustic characterised by arid and semi-arid climates. He prompt inserting water assortment containers reminiscent of tanks, barrels or bins on the finish of rainwater pipes coming down from roofs. This harvested water can then be used for actions reminiscent of washing vehicles and stairs, and watering lawns, offering a sensible measure for each water conservation and flood prevention.
Furthermore, Kadıoğlu proposed slowing down floor flows and facilitating underground absorption by creating gentle soil boundaries. He really helpful protecting naked soil surfaces with mulch to cut back evaporation, permitting the underground water to nourish plant roots. He offered an instance from 2015 in Ankara, the place a 100-square-meter (1,076.39-square-foot) roof space might retailer roughly 38,000 liters (10,038.54 gallons) of rainwater, equal to flushing a rest room 6,300 occasions per 12 months.
The professor urged people to calculate potential water financial savings primarily based on the typical annual rainfall of their area, multiplied by the sq. meters of their buildings, to realize insights into achievable water conservation measures.
