Why is the wind so warm in May?
Winds are warm in May because of gradual spring warming, increased solar radiation, rising surface temperatures and increased moisture content in the atmosphere. The change of atmospheric circulation and the northward movement of the subtropical high belt bring the warm air mass. In addition, human activities such as urban heat island effect and air pollution also affect wind temperature.
Climatic characteristics in May
Is the end of spring, but also the prelude to summer, vegetation began to flourish, the air filled with vibrant atmosphere.
The sun becomes more beautiful, the sky is blue, and occasionally a few white clouds drift by, for this beautiful season added a bit of poetry.
The river thaws, the water ripples, the fish play in the water, everything is full of vitality in this warm May.
May's climate, like a beautiful poem, people intoxicated, do not want to leave.
Climatic characteristics in May
May winds are warm because solar radiation increases and surface temperatures rise, warming the air.
Afternoon sun on the earth, warm, as if to tell the gentle spring.
With the replacement of the season, the breeze, bring a trace of moist atmosphere.
In this warm season, everything is full of life.
Climatic characteristics in May
The sky in May was bright blue, the sun shone through the clouds and the temperature warmed up.
The morning dew glistened on the tips of the grass, and the evening breeze caressed the cheeks, bringing the smell of spring.
Rain is no longer a cold blow, but gently moistening all things, so that the earth full of vitality.
The influence of atmospheric circulation
In May, the atmospheric circulation showed a new change, the subtropical high began to move northward, and the resulting warm air mass brought stability to the weather.
The heating mass gradually covered, making the temperature gradually rise, people began to feel the breath of summer approaching.
This change in atmospheric circulation has not only affected China, but also had a subtle impact on the global climate.
The influence of atmospheric circulation
As the warm air mass moves northward, the winds along the way warm.
As the warm air mass advanced, the temperature of the air gradually rose.
This increase in temperature has made the climate in the north more temperate.
The movement of the warm air mass affects the entire atmospheric circulation.
The influence of atmospheric circulation
The formation of warm and moist air, the wind becomes moist in May, plant growth and crop sowing can benefit.
Humid climate, for the earth covered with green, brought vitality.
The wind, brought water, brought hope, brought the joy of harvest.
Warm and moist air, as the care of nature, guarding the growth of crops.
Wet May, let all things grow, let crops thrive.
Atmospheric circulation, pregnant with vitality, nourish the earth.
The influence of topography and sea-land distribution
Wind temperature in May is deeply influenced by the topography and the distribution of land and sea. The vast ocean can bring more moderate air currents.
The continental margins, due to differences in the thermal properties of land and sea, often form certain types of climate, such as the monsoon climate, which is particularly pronounced in May.
The difference of sea-land distribution also directly leads to the difference of climate zone, and then affects the distribution of wind temperature in May.
The influence of topography and sea-land distribution
Mountains stand to block the wind, mountain wind speed increased, but the temperature decreased; the plains are wide, wind speed decreased, the temperature is relatively high.
The wind sped through the mountains, and the temperature was low; on the plains, it was calm, and the temperature was warm as spring.
At the top of the mountains, the wind is strong and the temperature is low.
The influence of topography and sea-land distribution
The regulation of the ocean can not be ignored. The wind in coastal areas is relatively stable and the wind is relatively warm.
The distribution of land and sea affects the climate, the coastal areas are affected by the ocean, the climate is mild, the inland is dry and changeable.
The vast area of the ocean makes it a huge force for climate regulation, regulating temperature and precipitation and affecting global climate.
Section 4 Impact of Human Activities
The wind temperature in May became hotter, as if telling the traces of human activity.
Smoke from factory chimneys made the sky lose its former blue.
Cars shuttling through the city emit carbon dioxide, causing temperatures to rise.
Forests are being cut down, soil is eroding and water sources are drying up.
The effects of human activity make the wind temperature in May even more worrying.
Section 4 Impact of Human Activities
The urban heat island effect significantly increases the urban regional temperature and wind speed.
High-rise buildings in dense areas, air circulation blocked, heat is not easy to dissipate.
Road hardening and greening are reduced, the ability to absorb solar radiation is reduced, and the surface temperature is increased.
Heat and waste heat emissions from human life aggravate the urban heat island effect.
Section 4 Impact of Human Activities
The emission of air pollutants changes the temperature of the wind, and the temperature fluctuates significantly during the propagation.
The pollution gas diffuses, the wind belt temperature changes gradually, affects the climate balance.
Wind direction is affected by pollutants, temperatures are volatile and ecosystems are disturbed.
