•Today I learned that the Low-Pressure Area, low or depression, is a region where the atmospheric pressure at sea level is lower than that of surrounding locations. Low-pressure systems form under areas of wind divergence which occur in upper levels of the troposphere. The formation process of a low-pressure area is known as cyclogenesis. Within the field of atmospheric dynamics, areas of wind divergence aloft occur in two areas. The first area is on the east side of upper troughs which form half of a Rossby wave within the Westerlies (a trough with large wavelength which extends through the troposphere). A second area of wind divergence aloft occurs ahead of embedded shortwave troughs which are of smaller wavelength. Diverging winds aloft ahead of these troughs cause atmospheric lift within the troposphere below, which lowers surface pressures as upward motion partially counteracts the force of gravity.
• I will apply my learnings and insights in sharing information about this phenomenon in my everyday life to become aware if what will happen when there is a Low-pressure area.
• Learning about this phenomenon are important because if we do not know what are the effects of this phenomena how can we able to prepare ourselves in such situations like this.
• On a larger scale, I will share my learnings in these phenomena to help others be aware and for them to be prepared on the things that might happen during this phenomena.
• I need to know more about Low-pressure area, its effect in our everyday life.
this really helped me a lot
