But if you develop persistent muscle weakness, or muscle weakness with no apparent cause or normal explanation, it may be a sign of an underlying health problem. Voluntary muscle contractions are usually generated when your brain sends a signal through your spinal cord and nerves to a muscle.
Of these factors, only rising sea surface temperatures was found to influence hurricane intensity in a statistically significant way over a long-term basis. The other factors affected hurricane activity on short time scales only. rise in the world's sea surface temperatures was the primary contributor to the formation of stronger hurricanes since 1970, a new study reports.
Best Answer: Because water heats and cools much slower than air, these large bodies of water have a moderating effect on land temperatures. In spring, when air temps over land are getting warmer, the body of water, which stays cooler much longer, cools the air immediately surrounding it. Likewise, in fall and winter, when cold air spreads over the land mass, these bodies of water retain their warmth, preventing temps from getting as cold around them. That is the effect that lakes have on land temperatures. The prevailing winds are also a large factor. Oceans provide land and sea breezes.
