Both are natural phenomena.

The bone cyclones and storms These are natural phenomena that have a relationship between them. However, their classification depends on their degree of mortality and the strength of their winds. For example, to understand what a tropical storm is, one must first know what a tropical cyclone is, such as the one that occurs in northern Peru. (Yaku Cyclone)and in the following note we leave you all the details.

According to IDEA (Institute of Hydrology, Meteorology and Environmental Studies), is a low pressure system that develops over tropical and subtropical waters, and has a closed circulation of the wind around a well-defined center (core). It is a rotating system given under certain conditions of the ocean and atmosphere. There must be an ocean temperature at or above 27 degrees Celsius and there must be a circulation in the winds that gives greater force to the counter-clockwise rotation to consolidate the cyclone as such.

The Rímac, Chillón and Huaycoloro rivers are on red alert due to increased flows.

In addition, all the radiation that comes from the sun and generates evaporation feeds this type of system and as they find more conditions in the ocean and atmosphere to feed on, they gain in intensity and category. .

However, tropical cyclones have different phases depending on the intensity of their winds around a central core. The categories are:

Tropical pressure (cyclone): less than 63 kilometers per hour

tropical storm: between 63 and 119 kilometers per hour

Hurricanes: They have 5 categories and start from 119 kilometers for now

  • Category 1 hurricanes: maximum sustained winds have speeds between 119 and 153 km/h.
  • Category 2 hurricanes: maximum sustained winds have speeds between 154 and 177 km/h.
  • Category 3 hurricanes: maximum sustained winds have speeds between 178 and 209 km/h.
  • Category 4 hurricanes: maximum sustained winds have a speed between 210 and 249 km/h.
  • Category 5 hurricanes: maximum sustained winds have speeds greater than 249 km/h.

Therefore, when the intensity of the winds around a central core atAt an intensity greater than 63 kilometers per hour and less than 119, we are facing a tropical storm. It is much more dangerous than a tropical cyclone. Hurricanes are of an even higher level.

They pose one of the greatest threats to life and property. They carry different hazards that can significantly affect life and property, such as storm surges, floods, extreme winds, tornadoes and lightning. When combined, these hazards interact with each other and greatly increase the potential for loss of life and property damage.

For example, over the past 50 years in the United States, 1,942 tropical cyclones have claimed the lives of more than 779,000 people and caused billions of dollars in economic losses.

He National Institute of Civil Protection (Indeci) released a series of recommendations that people should take into account when they are inside their homes or when they go out in the streets that could be flooded.

Recommendations:

– Do not touch wires, poles or electrical appliances if you are wet or standing in water. Watch out for mailboxes or drain pipes that can collapse.

– Do not come into contact with sewage, which can cause infectious diseases.

– Be careful where you step, because in the puddles there may be glass, cans or other objects that can hurt you.

– If you are driving or using public transport, slow down and do not stop in areas where a large amount of water may flow. Do not run or try to run or other objects that can hurt you while riding.

The intense rain that fell on Lima throughout the morning of March 14 and 15 flooded part of the central highway in Santa Clara. Several vehicles got stuck because the water affected their engines. Drivers were asked not to cross the area and to avoid going to Chosica, a neighborhood affected by the mudslides.

Additionally, around 27 streams were activated and overflowed in the Peruvian capital, affecting dozens of homes and leaving destruction and desolation in their wake. Senamhi said rainfall will continue in Lima and river overflows are estimated. There are roads blocked by mudslides.
