Why can't meteorologists call the weather correctly every time? Blame the battle of the weather models.
Images created by NASA with satellite data helped the U.S. Department of Agriculture analyze outbreak patterns for southern pine beetles in Alabama, in spring 2016.
Big data open-access publishing and other advances offer ecologists the ability to forecast events like pest outbreaks over days and seasons rather than decades. But scholars need to seize this opportunity.
Knowing about hailstones in advance would be preferable.

New "dual-pol" weather radars promise to spot large hailstones forming inside thunderstorms, giving people a heads-up when it's about to hail.
Cape Town’s drought and associated water shortage has escalated disaster level.
Cape Town promised alternative water sources with the ongoing drought being declared a disaster. Its main strategy is water rationing but climate models are also being used.
The rainfall from Harvey has now exceeded the amount from the previous record-bearer, Tropical Storm Amelia in 1978.

An expert in extreme weather events explains why the rain – and thus flooding – associated with Hurricane Harvey has been 'unprecedented.'
The stereotype of the conventionally attractive female weather reporter is alive and well on Australian television.
The weather segment at the end of news bulletins has stuck to a familiar format for more than 50 years. But the question of who should actually present the weather has been in a constant state of flux.
Farmers don’t get efficient information on weather changes, improving data can change this.
Information to weather changes is often unavailable to Africa's farmers and even if it does exist, the quality is poor or inaccessible to those who need it most.
Hurricane Matthew approaching the east coast of Florida on Oct. 6, 2016.
Two atmospheric scientists explain how they weigh evidence such as ocean temperatures, wind speeds and other climate patterns to predict how many Atlantic hurricanes are likely to form this year.
All tropical cyclones in the 2012 Atlantic hurricane season, with their locations shown at six-hour intervals and color representing maximum wind speed.
Major hurricanes threaten millions of people and billions of dollars in property along the Atlantic coast. Here experts advise on preparing, understanding forecasts and recovering after a storm.

Weather forecasting stopped looking for patterns in the past, and started using numbers to look solidly at the future.
Sixteen of the 17 hottest years have occurred this century and we know it’s because of a changing climate, not changes in weather.
For the third consecutive year, it's the hottest year ever. A climate scientist explains how these predictions are made and why they're completely different from forecasting the weather.
A big part of South Africa’s appeal lies in its good weather. Climate change poses a risk to the tourism industry.

South Africa's weather is very attractive to international visitors. Climate change could alter their perceptions unless mitigation strategies are put in place.

President Trump's 2018 budget request cuts funding for NASA Earth observation research and cancels four missions. Weather forecasters, businesses, scientists and the armed forces rely on this data.
Damage from Hurricane Matthew in North Charleston, South Carolina, October 2016.
Conservative commentators accused government officials last week of hyping risks from Hurricane Matthew. A meteorologist explains why this is impossible in the internet era.
Data about farms’ financial situation as well as the weather could help identify those most vulnerable to drought.
Forecasting drought should be about more than weather – to help those likely to be hit hardest, we need financial and even health data too.
Hurricane Pali churns over the eastern Pacific on January 11.

January hurricanes are rare events, but two have already formed this month. Atmospheric scientist Adam Sobel explains the conditions that generated Pali and Alex.
Are you dreaming of a festive win at the bookies? Here are your chances.
Simpler climate models could help more people understand the processes behind the predictions.
Climate models are complicated - and necessarily so if they are to recreate our complex world. But a new, simpler climate model aims to take some of the mystery out of the art of climate modelling.
One of the world's top weather forecasting services just lost a major contract.
