Climate suitability for Locust Migration Flight

Migration and long march of adult locusts is a function of temperature, saturation deficit, wind velocity and direction, cloudiness and the upper atmospheric condition i.e. vertical distribution of atmospheric water vapour and mixing zones of upper atmosphere especially in the convergence zones. There is a minimum threshold temperature for flight muscle activation (greater than 17oC), on the other hand above 42 oC thermal inactivation of muscle take place and flight is rare. Most optimum temperature is nearer to 35 oC. Similar to air temperature, humidity also play role in maintaining water balance during flight. Threshold wind velocity required for flight of DL is 13 m/s as the swarms prefer to move passively downwind with +/-10 degree deviation along its direction. Below the threshold wing movement is limited to hopping and saltation. In a cloudy day however, locusts do not fly. All the above constraints were used in programming logic to evaluate the chances of flight.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
